Hiroshima Boy Nominated for Both the Edgar & Anthony Awards!

The Final Mas Arai Mystery

LA gardener Mas Arai returns to Hiroshima to bring his best friend’s ashes to a relative on a small island, only to be embroiled in the mysterious death of a teenage boy who was about the same age Mas was when he survived the atomic bomb in 1945.

Praise for Hiroshima Boy

Hiroshima Boy is the final appearance for Mas Arai, the protagonist of Altadena author Naomi Hirahara’s seven-book mystery series. Hirahara has crafted a fitting “finale” to this Edgar Award-winning series: Mas, the 85-year-old retired L.A. gardener and amateur detective, returns to his birthplace of Japan to deliver the ashes of his best friend to an island off of Hiroshima. Hirahara would seem to be telling the quiet story of a coming home, but it’s also a metaphorical ghost story — the ghost images of the Japan Mas remembers, the atomic bomb and its far-reaching shadow, Mas’s dead friend, and a young boy whose body Mas discovers during his visit. The subsequent investigation launches a compelling plot, but the heart of the book, where it transcends its genre, is Hirahara’s moving exploration of the ways people are haunted.”
The Los Angeles Daily News, which included Hiroshima Boy in their list of “5 Wonderful New Books for Southern California Readers

“I’ve always admired Naomi Hirahara’s Mas Arai. A brilliant, unique addition to mystery fiction from the very beginning, his character has straddled time, place, and culture, with roots in one of the most terrible acts of violence war has ever inflicted upon humanity. And Mas has prevailed while growing older in a country that does not always value the wisdom of its elders, or those who work with their hands. This may be the last entry in the series (really?), but I am sure readers will come to love Mas for years to come—he is one of a kind. Hiroshima Boy is a wonderful finale to a fine mystery series. Kudos to Naomi Hirahara.”
Jacqueline Winspear, author of the New York Times–bestselling Maisie Dobbs mysteries

“Hirahara is an Edgar-winning author, and her seventh and, we’re told,final Mas Arai novel is another winner, with Mas again showing flashes of Columbo, with, perhaps, an even finer nose for nuance. A memorable conclusion to a too-little-known series.”

“With Hiroshima Boy, Naomi Hirahara offers readers another fine, artfully understated story about a man who believes himself to be average, yet is anything but. Carrying the ashes of his deceased best friend, Mas Arai returns to Hiroshima, where he spent his childhood and was witness to the bomb that devastated the city and its populace. When Mas stumbles onto the body of a murdered boy, what began as a simple mission to keep a recent promise becomes a complex journey in understanding the past. Like a Zen poet, Hirahara creates a quiet surface with a powerful storm beneath. The novel purports to be the last in this Edgar Award–winning series. We can only hope that Naomi Hirahara has a change of heart.”
William Kent Krueger, New York Times–bestselling author of Ordinary Grace and the Cork O’Connor mysteries

“Edgar-winner Hirahara’s moving seventh and final Mas Arai mystery…. Hirahara has crafted a fitting ending to Mas’s journey from stricken Hiroshima to what he considers his real home in Altadena, California.”
Publishers Weekly

A “Must Read of 2018”

Praise for Sayonara Slam

“Written with heart, depth and pace, Hirahara’s sixth case is hard to put down.” — Kirkus Reviews

“In a genre in which unusual amateur sleuths are the norm, Mas Arai is in a class by himself.
— Oline Cogdill, Florida Sun-Sentinel and many other Tribune newspapers

“Hirahara crafts a superb whodunit.”
Daily Republic

“I’m off to find some more Hirahara.”
The Globe & Mail, Toronto

“Mas is a hyperobservant, methodical sleuth—a blend of Columbo and Hercule Poirot—but what makes this award-winning series shine is the way Hirahara takes readers inside her character’s head. A winner.” — Booklist

“Hirahara has crafted a pitch-perfect blend of mystery with threads of history in Sayonara Slam… a pleasingly multi-layered mystery that is both entertaining and thought-provoking.”
— Craig Sisterson, Crime Watch

“Mas Arai is a wholly original sleuth—reluctant, curmudgeonly, and irresistible. In Sayonara Slam, he delves into baseball, World War II, and the complex history between Japan and Korea, all while grappling with that most enduring mystery, love. Hirahara has created a story that’s both meaningful and great fun; you’ll be cheering until the very last play.”
— Nina Revoyr, author of Lost Canyon, Southland, and Wingshooters

“Hirahara is an Edgar-winning author, and her seventh and, we’re told, final Mas Arai novel is another winner, with Mas again showing flashes of Columbo, with, perhaps, an even finer nose for nuance. A memorable conclusion to a too-little-known series.” — Booklist
