    When she's convicted of her best friend Rose's brutal murder, she's designated a Class A--the most dangerous and manipulative criminal profile. To avoid prison, Signal signs on for a secret program for 18-and-under Class As and is whisked off to an abandoned sleep-away camp, where she and seven bunkmates will train as assassins. Yet even in the Teen Killers Club, Signal doesn't fit in. She's squeamish around blood. She's kind and empathetic. And her optimistic attitude is threatening to turn a group of ragtag maniacs into a team of close-knit friends. Maybe that's because Signal's not really a killer. She was framed for Rose's murder and only joined the program to escape, track down Rose's real killer, and clear her name. But Signal never planned on the sinister technologies that keep the campers confined. She never planned on the mysterious man in the woods determined to pick them off one by one. And she certainly never planned on falling in love. Signal's strategy is coming apart at the seams as the true killer prepares to strike again in Teen Killers Club.
