The Hooblers (The Cuban American Family Album, 1996, etc.) employ suspense, action, superstition, and mystery to entrance readers with this tale of 18th-century Japan and a boy's search for honor. Seikei, 14, is embarrassed to have been born into the merchant class and dreams of becoming a samurai. While on a business trip with his father, he witnesses the theft of a valuable ruby from a haughty samurai. Drawn into the case by Judge Ooka, a real historical figure, Seikei plunges into the chase. He finds himself in the company of Tomomi, a brilliant Kabuki actor and master of acrobatics and swordsmanship. Seikei begins to admire him, even though he knows that Tomomi is the thief and a Kirishitan, a member of a banned religious sect. But Tomomi plans much more than theft. He intends to expose and dishonor the man who destroyed his family; Seikei unwittingly becomes part of his plot, and gets the chance to fulfill his dream. The climatic scene of a play that exposes the real villain echoes the plot of Hamlet, and may work as an introduction to Shakespeare's play. Full of adventure, offering a vivid portrait of Shogun-era Japan, this is a remarkable novel. (Fiction. 12-14)
