When I finally hear the click of the latch on the dormitory door, I have only a second to brace myself before-"At Cate's isolated boarding school Killer is more than a game-it's an elite secret society. Members must avoid being "killed" during a series of thrilling pranks-and only the Game Master knows who the "killer" is. When Cate's finally invited to join The Guild of Assassins, she knows it's her ticket to finally feeling like she belongs. But when the game becomes all too real, the school threatens to shut it down. Cate will do anything to keep playing and save The Guild. But can she find the real assassin-before she's the next target?

Cate is looking forward to Killer Game—a school tradition of thrilling prank 'killings'. But what happens when the Game becomes real and it seems that she's the next target?
