Tool of war

This third book in a major series by a bestselling science fiction author, Printz Award winner, and National Book Award finalist is the gripping story of the most provocative character from his acclaimed novels Ship Breaker and The Drowned Cities. Tool, a half-man/half-beast designed for combat, is capable of so much more than his creators had ever dreamed. He has gone rogue from his pack of bioengineered "augments" and emerged a victorious leader of a pack of human soldier boys. But he is hunted relentlessly by someone determined to destroy him, who knows an alarming secret: Tool has found the way to resist his genetically ingrained impulses of submission and loyalty toward his masters ... The time is coming when Tool will embark on an all-out war against those who have enslaved him. From one of science fiction's undisputed masters comes a riveting page-turner that pulls no punches.
