You can't change your DNA . . . even when it says you're a murderer.When Davy tests positive for Homicidal Tendency Syndrome, aka "the kill gene," she loses everything. Once the perfect high school senior, she is uninvited from her prep school and abandoned by her friends and boyfriend. Even her parents are now afraid of her-although she's never hurt a fly. Davy doesn't feel any different, but genes don't lie. One day she will kill someone.Without any say in the matter, Davy is thrown into a special class for HTS carriers. She has no doubt the predictions are right about them, especially Sean, who already bears the "H" tattoo as proof of his violence. Yet when the world turns on the carriers, Sean is the only one she can trust. Maybe he's not as dangerous as he seems.Or maybe Davy is just as deadly.
