Touch is lethal. Love is dangerous. Nobody is safe. For fifty years, the Key Corporation has defended humanity against a deadly plague that spreads through touch. Lovers don't hold hands, or even kiss. Personal boundaries are valued above all. Break the laws, and you'll face execution. Elodie, a talented young nurse, believes in the mission of the Key and has never questioned the laws that control her life. But Elodie is forced to break the rules to find a terminal patient who's gone missing while under her care. From the outside, it seems the Key has given Aiden everything he could want--a purpose, an education, and a future. But Aiden knows more than he's letting on, and the dark secrets he's keeping could tear the Key's strict society apart. When Elodie and Aiden's lives collide, the fallout will be devastating. What do you do when the system that kept you safe is now on the hunt? Run.
