Sixteen-year-old Alaric discovers how to travel to an alternate reality, where his mother is alive and his place in the family is held by a girl named Naia.
Violet Ambrose is grappling with two major issues: Jay Heaton and her morbid secret ability. While the sixteen-year-old is confused by her new feelings for her best friend since childhood, she is more disturbed by her "power" to sense dead bodies—or at least those that have been murdered. Since she was a little girl, she has felt the echoes the dead leave behind in the world . . . and the imprints that attach to their killers. Violet has never considered her strange talent to be a gift; it mostly just led her to find dead birds her cat left for her. But now that a serial killer is terrorizing her small town, and the echoes of the local girls he's claimed haunt her daily, Violet realizes she might be the only person who can stop him. Despite his fierce protectiveness over her, Jay reluctantly agrees to help Violet find the murderer—and Violet is unnerved by her hope that Jay's intentions are much more than friendly. But even as she's falling intensely in love, Violet is getting closer and closer to discovering a killer . . . and becoming his prey herself.
In the class of the high school English teacher she has been haunting, Helen feels them: for the first time in 130 years, human eyes are looking at her. They belong to a boy, a boy who has not seemed remarkable until now. And Helen--terrified, but intrigued--is drawn to him. The fact that he is in a body and she is not presents this unlikely couple with their first challenge. But as the lovers struggle to find a way to be together, they begin to discover the secrets of their former lives and of the young people they come to possess.
