We look like you. We talk like you. We live among you. But we are not you. We can do things you dream of doing. We have powers you dream of having. We are stronger and faster than anything you have ever seen. We are the superheroes you worship in movies and comic books--but we are real.Our plan was to grow, and train, and become strong, and become one, and fight them. But they found us and started hunting us first. Now all of us are running. Spending our lives in shadows, in places where no one would look, blending in. We have lived among you without you knowing.But they know.They caught Number One in Malaysia.Number Two in England.And Number Three in Kenya.They killed them all.I am Number Four.I am next.

    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 that 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 the 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, she realizes she might be the only person who can stop him.Despite his fierce protectiveness over her, Jay reluctantly agrees to help Violet on her quest to 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.
