Set in a dark future devastated by climate change, Tool of War is the third book in a major adventure series by a bestselling and award-winning science fiction author and starring the most provocative character from the acclaimed novels Ship Breaker and The Drowned Cities . In this gripping, eerily prescient sci-fi thriller that Kirkus described as "masterful," Tool—a half-man/half-beast designed for combat—proves himself 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 and all-too-timely page-turner that explores the intricate relationships connecting hunter and prey, master and enslaved, human and monster. "Suzanne Collins may have put dystopian literature on the YA map with 'The Hunger Games'...but Bacigalupi is one of the genre's masters, employing inventively terrifying details in equally imaginative story lines." — Los Angeles Times
