About this book

Book Summary

A sweeping and suspenseful novel of love and war, set in Japan during the final days of World War II, with a shocking historical premise: three atomic bombs were actually delivered to the Pacific—not two—and when one of them falls into the hands of the Japanese, the fate of a couple that has been separated from one another becomes entangled with the fate of this terrifying new device.

War has taken everything from physicist Keizo Kan. His young daughter was killed in the Great Tokyo Air Raid, and now his Japanese American wife, Noriko, has been imprisoned by the brutal Thought Police. An American bomber, downed over Japan on the first day of August 1945, offers the scientist a surprising chance at salvation. The Imperial Army dispatches him to examine an unusual device recovered from the plane's wreckage—a bomb containing uranium—and tells him that if he can unlock its mysteries, his wife will be released.

Working in secrecy under crushing pressure, Kan begins to disassemble the bomb and study its components. One of his assistants falls ill after mishandling the uranium, but his alarming deterioration, and Kan's own symptoms, are ignored by the commanding officer demanding results. Desperate to stave off Japan's surrender to the Allies, the army will stop at nothing to harness the weapon's unimaginable power. They order Kan to prepare the bomb for manual detonation over a target—a suicide mission that will strike a devastating blow against the Americans. Kan is soon confronted with a series of agonizing decisions that will test his courage, his loyalty, and his very humanity.

An extraordinary debut novel that is the result of twenty-seven years of work by its author, Daikon is a gripping and powerfully moving saga that calls to mind such classics as Cold Mountain and From Here to Eternity. It is set amid the chaos and despair of the world's third largest city lying in ruins, its population starving and its leadership under escalating assault from without and within. Here is a haunting epic of love, survival, and impossible choices that introduces a singular new voice on the literary landscape.

Please be aware that this discussion guide will contain spoilers!
  1. The Prologue is notably different from the rest of Daikon in many ways. Why do you think the author chose to begin with this romantic, nostalgic scene in America? Do you think the desired effect is achieved?
  2. Daikon is ultimately a story of homecoming. At the end of the book, Keizo, Noriko, and Yagi all experience coming home or rebuilding home, in different ways. Did you find yourself drawn to one of their stories more than the others?
  3. At the end of the book, it is revealed that Aiko's name, which means "child of love," is hidden within "Daikon." A "child of love" nested in a bomb. How is this symbolic of the motivations Keizo has, and the choices he makes, toward the end of the war?
  4. Though they are both starkly ...

Media Reviews

"An engrossing and thought-provoking novel...The plot feels entirely plausible, and none of the characters fit any obvious stereotypes...The author's research is impressive as he describes how the bomb is designed to work, the tensions within the Japanese power structure, and details of Japanese culture." —Kirkus Reviews (starred review)

"Thrilling...Builds to a pulse-pounding climax. The result is the most imaginative take on Hiroshima since Edwin Corley's The Jesus Factor." —Publishers Weekly (starred review)

"Propelled by the tensions between hard-liners and those open to surrender...[Daikon is] a realistic and tightly plotted narrative told through Japanese eyes." —Booklist (starred review)

"Daikon is a gripping and fascinating work of historical fiction that's so convincing I felt like I'd stumbled onto an extraordinary World War II documentary with indelible characters and haunting footage from a vantage I'd never imagined. Daikon will sweep you away." —Jess Walter, #1 New York Times bestselling author of Beautiful Ruins

"Daikon is an exhilarating tale set amid the extraordinary devastation and despair of Japan's last days in World War II. Carefully researched, thoroughly convincing, and utterly compelling. I loved this book, and you will love it too." —Arthur Golden, New York Times bestselling author of Memoirs of a Geisha

Fabulous alternative historical fiction
Daikon combines the best of alternative historical fiction and a thriller. The premise is that in WWII, the Americans had not two but three atomic bombs ready to drop on Japan. But the first plane is shot out of the sky and the bomb doesn’t detonate and is recovered by the Japanese. A Japanese physicist, involved in their own efforts to design an atomic bomb, is brought in to try and determine how to use it against the US.
Hawley does a great job of setting the scene in time and place. The description of Hiroshima after it was bombed caused my stomach to roil. Hawley also doesn’t sugarcoat the effects of being near enriched uranium.

The characters are well fleshed out. Keizo Kan, the scientist, really wrestles with what he’s being asked to do, especially after seeing Hiroshima. What had been a hypothetical theory now has real world consequences. But the Thought Police are holding his American Wife and he is torn between wanting to rescue her and the death of hundreds of thousands more. And Colonel Sagara, overseeing the “program”, embodies the no surrender attitude.

Hawley has done his research and he imparts it to the reader without slowing down the story. I finally understand the mechanics of the atomic bomb. Be sure to read the Author’s Note which gives more background on what was happening in Japan during the last months of the war.

My thanks to Netgalley and Simon & Schuster for an advance copy of this book.
