Beyond a shadow of a doubt, B Smith has decided to live-and to fight for good as long as possible. However, London is overridden with the brain-eating undead and swarming with human mercenaries whose sense of right and wrong dissolved when society did. When they lay a trap, B is captured. And it’ll take dozens of battles-and the fight of a lifetime-to escape. Filled with gripping, bloody action sequences, the sixth book in Darren Shan’s horrifying Zom-B series promises the fright-and the fight-of your life.
