Japan, 1620: A mysterious shipwreck has left cabin boy Simon Grey stranded in an unfamiliar, dangerous land.

He hoped that a long sea voyage would provide some relief from his “gift” of seeing ghosts everywhere on land. Instead, he finds that his ability draws him into the shadowy world of yokai, the spirits and monsters that roam Japan by night. Together with the mysterious Oyuki, daughter of an English sailor-turned-samurai, Simon must earn the yokai’s trust and help, while staying one step ahead of the Shogun’s guards and an evil sorcerer determined to discover the “secret” of Simon’s powers.

As they struggle to stay alive and find a way home, Simon and Oyuki deal with friends and foes from both sides of the grave.

Simon Grey and the March of a Hundred Ghosts is a gripping fantasy adventure that will appeal to fans of the Percy Jackson and Young Samurai series.


“This exciting adventure filled with humor, great characters, and lively writing will drive young readers under the covers with flashlights to read late into the night. This is a winner!” – San Francisco Book Review
