About the author

David Kudler headshot
David Kudler

David Kudler is an author and editor living just north of the Golden Gate Bridge with his wife, actor/teacher/author Maura Vaughn, their author-to-be daughters, and their (apparently) non-literary cats.

He is the founder, publisher, and editor-in-chief for Stillpoint Digital Press. For over two decades, he served as managing editor at the Joseph Campbell Foundation, where he edited three posthumous volumes of Campbell’s previously unpublished work (Pathways to Bliss, Myths of Light and Sake & Satori) and managed the publication of over a hundred print, ebook, print, audio, and video titles, including the first new edition of the seminal Hero with a Thousand Faces since the author’s death.

His children’s picture book The Seven Gods of Luck (Illustrated by Linda Finch) was published by Houghton Mifflin in 1997. Based on an old Japanese folktale about a young girl and boy who are rewarded for their generosity. The New York Times called The Seven Gods of Luck “a sweetly illustrated retelling,” while School Library Journal extolled the “well-paced, carefully plotted text,” calling it “a lively adaptation.” Stillpoint Digital Press reissued the book in 2012 as the first title in the Winter Tales series. With wife Maura Vaughn, Kudler has adapted two other folktales as part of the series: Shlomo Travels to Warsaw and How Raven Brought Back the Light.

Risuko, his young-adult historical adventure novel, was released in June, 2016. Set in sixteenth century Japan, Risuko follows the adventures of a young woman pulled into a plot that may reunite a war-torn Japan — or may destroy it. The first sequel, Bright Eyes, hit shelves in 2022, and Kano, the third book in the series, is scheduled for release on March 1, 2024

Risuko reviews

Risuko is an artfully crafted novel that evokes a heavy sense of place and enchantment. The world in which Risuko lives is filled with lords and ladies, spies, and complicated battles, not all of which are fought out on the field. Lady Chiyome especially is an interesting figure, with a depth that is mirrored in the complicated relationships in the rest of the tale. Risuko becomes an interesting blend of both the historical and the magical, and the stakes of the story are enormous. In turn, Risuko’s development and evolution are fascinating to watch in this powerful and relentless coming-of-age adventure. — Foreword Reviews

A tight, exciting, and thoughtful first volume in what promises to be a fine series about a female ninja. — Kirkus Reviews

It is easy to invest in the characters, and once the reader starts this book, it’s almost impossible to put it down. Risuko goes through a lot of character growth throughout the book. An entertaining story with excellent writing and haunting descriptions, a relatable heroine, and fast-paced writing.InD’tale Magazine

I especially loved the characters. I loved all of them and that doesn’t happen very often I can tell you. I was able to connect with all of them and I loved the main character’s interactions with everyone. —Dilara Çelik, Deceived by Daydreams

Risuko is written in a language that sings, capturing the reader from the first moment you open the page. The book draws you in and grips you, refusing to let go until those final few paragraphs. I blasted through Risuko’s two hundred and thirty-six pages in a mere four days, and can’t wait for the next installment. —Rachel, MyAccidentalBookAddiction

Vividly portrayed, flush with cultural detail, and smoothly written.” — BookLife

Bright Eyes Reviews

“Once again David Kudler has fully succeeded as a novelist with a genuine flair for historical fiction populated by memorably crafted characters and decidedly entertaining plot twists and turns. Like the first novel in the author’s ‘Seasons of the Sword’ series, Bright Eyes is imaginative, original, exceptionally well written, and highly recommended” – Midwest Book Review

“The author has built an impressive imaginative world, yet strikes a balance by including elements of Japanese culture so it feels realistic. While readers will benefit from having read the first book in the series, Risuko: A Kunoichi Tale, the story is clear and compelling enough to stand alone. This well-written novel immerses the reader in the Japanese culture through vocabulary and tradition. The plot is easy to follow, with a balance between detail and conversation to convey the story. The use of the Japanese vocabulary throughout helps establish a grounded setting, and the glossary will prove helpful to the reader. The author crafts a highly unique and captivating world in the pages of Bright Eyes.” — BookLife

“David Kudler crafts an enthralling. unputdownable tale due in no small part to his outstanding world building. He ties enough aspects of real-life feudal Japanese culture to give the perfect balance of reality in this fictional world. […] The well-crafted mystery, well-honed history and world-building, and Risuko’s adventurousness leave the reader wanting more.” — Shailyn Rogers, Ind’Tale Magazine

Comments from early readers

Risuko has a strong sense of time and place, immersing the reader in a compelling tale of intrigue. Because we enter the fray alongside Risuko herself we meet the characters and learn the political machinations alongside her – allowing her to unravel the mysteries for us. Beautifully paced, we leave wanting more but not feeling cheated (as often happens with a “book 1”) — Helen

I like well developed characters and good writing. This book has both. — Ania Mieszkowska

I was able to connect with every character and their interactions with others, which is not always the case when I read books.—Dilara Çelik

This book is AMAZING! The plot is interesting, the characters are interesting, just EVERYTHING was great.—Melody A.

I loved the depth of characters and how despite their strength they struggled with what was right. — Rachel S

I really enjoyed the characters that were developed during the book. Risuko was well fleshed out and her feelings seeped through the page, making for a great main character! —  Breanna

The characters, and the careful yet detailed way Japan is presented to the reader – the culture is handled incredibly well. — Ventureadlaxre

Risuko is a rich story line with incredible attention to detail that is hard to put down, luckily I was on a long plane ride and was able to finish the book in one sitting! The innocence of Risuko makes this book even more charming and a great read for both young and old.  Kelley

Interview questions

What was your inspiration to write Risuko?

Some years ago, I was leafing through an old issue of New Moon, a magazine of my daughters’, and came across an article titled “Killer Accessories.” Very briefly, it told the story of a Japanese noblewoman, a war widow by the name of Mochizuki Chiyome, who had trained a group of women called kunoichi during the period in Japanese history known as Sengoku Jidai — the Civil War era that lasted from 1467 to 1603 (by the Western calendar).

The article described how, under the pretense of running a school for shrine maidens, Lady Chiyome built a small army of “dangerous flowers.” It showed an assortment of the kunoichi’s specialized weapons — fans with knife blades, fake fingernails with poisoned tips, reinforced parasols that could be used as shields — and finally said that Lady Chiyome’s army had faded into obscurity after the death of their patron, Takeda Shingen.

Well, I thought, there’s a story that has to be written! And I began to do research, and I started to think about how to bring this story — and the amazing, awful period during which it took place — to life.

The other main spark was my youngest daughter, who liked to leap before looking.

One day when she was about four, I was watching her in a playground. She was playing with her friend Lucas, some wild, two-person game of tag.

Lucas’s mom and I were chatting, when suddenly she said, “Where are the kids?”

We heard a call from above us. They were way up a small pine tree on the edge of the playground. Waving.

Now, I have what the late Sir Terry Pratchett called “a great respect for depths.” When my heart had dislodged itself from my throat, I asked Julia and Lucas to come down as carefully as they could.

Which, thankfully, they did.

A few weeks later, I wrote the first draft of what is now the first chapter of the book. The girl up in the pine tree didn’t have a name, and I didn’t know where the story was going. That would take a long, long time. But I knew that she was going to be a kunoichi.

What genre does your book fall under?

Many. It’s a young-adult/middle-grade historical adventure novel. That’s four right there, right? It’s also a coming-of-age story, as well as being a variation on the boarding-school genre. Maybe I’ll get pirates in there somewhere. And kunoichi are sort of like ninjas. Only not.

When I was writing Risuko, I was thinking about the wonderful fantasy adventure books that my daughters and I loved to read — Harry Potter, Artemis Fowl, Percy Jackson, and the rest.  Two questions occurred to me:

  1. Why couldn’t historical fiction be as engaging and exciting as fantasy?
  2. Why aren’t the protagonists girls?

In the past few years we’ve seen a number of strong young women headlining popular teen books — but they remain the exception rather than the rule. I’d like to continue chipping away at that imbalance. (My youngest daughter informed me with pride that Risuko passed the Bechdel Test with flying colors. I had to look it up — but was pleased to not only was she right, but the book passes the reverse Bechdel. W00t.)

How long did it take you to write the first draft of your manuscript?

Interesting question. I wrote the first chapter, then did whole bunch of historical research — it’s one thing to have an interest in a period and quite another to write a historical novel set in that period. After a couple of months, I felt as if I had a pretty good sense of what I needed to know for the purposes of my story. (It was tough, however, finding accurate information about the daily lives of people in sixteenth century Japan; huge battles, sure, but not what they ate!) I threw together a pretty sketchy outline of the story and began plowing away at the opening chapters.

Then, about twenty chapters in, I hit a wall. (Novels being what they are, the spot where I got stuck now comes much earlier in the book.)

I knew where I wanted the story to go, but couldn’t see exactly how to get Risuko and Co. there. I put the book aside for a bit. Then I got involved in a huge editing project, and suddenly four years had passed since I had looked at the manuscript. Four years! I opened the file, looked at the outline, and realized two things: first of all, my outline was actually for a three- or perhaps four-novel series, and second, I finally knew how to get Risuko back to where she needed to be. I started work again, got bogged down… But Brenda and Donal Brown, friends to whom I’d given the opening chapters, kept asking me to how it turned out. Asking very persistently. I offered to give them the outline, but no — they would only be satisfied with a finished draft. Well, then, a finished draft I would give them!

I finally completed the first draft of Risuko nearly eight years after I read that article that sparked the idea. I began the process of revision, and in the mean time the Browns (who deserve some sort of medal for this among a million other acts) passed the manuscript along to a neighbor, Danielle Svetcov, who happened to be a literary agent. She signed the book that summer, and worked with me to revise it. I rewrote the opening chapter a half a dozen times, eliminated a number of secondary characters who didn’t add anything, cut the first third of the book in half — and then added a new subplot in. Whew! Writing is hard, but rewriting is harder.

The book finally came out in June, 2016 — over a decade after I’d read the article in New Moon about Lady Chiyome’s school for kunoichi that first inspired me.

Why are you so interested in Japan?
Seven Gods of Luck

I grew up in California in a house full of Japan. My parents had lived in northern Japan for three years before I was born, and so when I was a child I read Japanese stories, and my brother and I even celebrated Japanese holidays like Childrens’ Day (May 5). There was Japanese art and craftwork throughout our home, including, on the wall of our living room, a set of seven small, hand-carved wooden masks: the Seven Gods of Luck. My father was a big fan of Westerns, but an even bigger fan of samurai epics like The Seven Samurai (which inspired The Magnificent Seven), Rashomon, Throne of Blood (a retelling of Macbeth), and Kagemusha (which features a character based on Takeda Shingen).  Other kids on my street wanted to be cowboys; I wanted to be Toshiro Mifune.

I’ve always been fascinated by the Sengoku Era, and I’m not alone. There’s a reason that there are so many movies and books set during this period. It occupies a similar spot in Japan’s imagination that the Old West does in America—a time when life was horrifically hard, but anything was possible. Before that time, Japan had been run more or less smoothly by a series of warlords (shōgun) since the twelfth century (the time of the original Lady Murasaki, author of what has been called the world’s first true novel, The Tale of Genji). The warlord ruled the nation on behalf of the emperor, often from the imperial city, Kyōto, but sometimes from other cities, such as Kamakura.

Now, a teacher of mine liked to point out that good marriages make bad stories. I think you could say that peaceful times make boring history—not a bad thing for the people living through them, but much less interesting for those of us looking back. It’s a good thing, then, for people like me that in the late fifteenth century a series of natural disasters (earthquakes, famine, etc.), combined with weak leadership by the Ashikaga shōguns, led the lords of Japan’s provinces to rebel.

For the next a hundred years and more—starting at around the same time as the English Wars of the Roses and ending just before the establishment of the Jamestown colony in Virginia—groups of Japanese lords fought to unite the nation behind one or another of their number. Whenever one of the alliances seemed poised to bring the empire under its control, one or more of the allies would split off, unite with lords from the opposition, and the cycle of violence would start again. A map of the country would indeed have looked very much like Lady Chiyome’s in the book: a war of swirling colors marking shifting allegiances.

Did kunoichi really exist?

That is a very interesting question, and one that might be answered in a number of ways:

Yes. No. Maybe.

For myself, the answer is perhaps, and if not, they should have.

During the time in which this book is set, an alliance led by Oda Nobunaga had come close to achieving unification of the country. Takeda Shingen and Matsudaira Motayasu (who would later be known by quite a different name) were among his chief allies. We have records of huge battles involving tens of thousands of soldiers. We know there were spies and assassins.

Doesn’t it seem likely that at least some of those involved were female?

Today, most countries have women serving proudly in their military forces. History is full of stories of women who have served—and served well—as soldiers, either disguised as men, or, rarely, in the open. When I was young, I loved the ancient Greek tales of the legendary Amazons, the fiercest of the foes, but not all of the stories are myths. Boudica, a British queen, led troops against the Roman legions, while Joan of Arc led a French army against the English during the Hundred Years War. During the American Civil War, we have records of hundreds of women soldiers serving (and dying) in the armies of both the Union and the Confederacy. Wars affected women as much as men; it makes sense that women would seek to participate, to help determine their outcome. In most cultures, however, women were seen as weaker and gentler; they were forbidden from dressing as men (on pain of death in many countries—Japan among them), and they were forbidden from fighting openly.

It makes perfect sense that a widow like Mochizuki Chiyome would have sought a way to help end the chaos and bloodshed that had gripped Japan for over a century by using the tools that she had at hand. It makes sense that she would see in the girls orphaned by a century of war the opportunity to build an army unlike any that had marched across Japan’s blood-soaked hills and fields.

There’s another reason that this period fascinates me and so many others: Japanese society had been (and would later once more be) remarkably rigid, binding each individual to the traditional role of his or her class, clan, and gender. After a hundred years of war and upheaval, men and women were no longer as tightly bound; they could change their circumstances in life through their own abilities. Though duty and family honor remained the most powerful forces in Japanese society, the daughter of a shamed samurai, for example, might indeed act to regain her family’s honor.

So, to return to the opening question: Where the kunoichi real?

Again, I answer: Yes. No. Maybe.

But whether an army of women spies, bodyguards and assassins dressed as shrine maidens truly wandered across Sengoku-era Japan, the conditions for such a force existed. And that’s the world in which Risuko’s tale unfolds.
