Book excerpt: From the author of Undead and Unfed comes a completely gripping, psychological whodunnit that will keep readers guessing to the last page. At Cate’s isolated boarding school, Killer Game is a tradition. Only a select few are invited to play. They must avoid being ‘killed’ by a series of thrilling pranks, and identify the ‘murderer’. But this time, it’s different: the game stops feeling fake and starts getting dangerous—and Cate’s the next target. Can they find the culprit … before it’s too late?
