Echoes

Shannon might be going crazy, and she couldn't be happier. It seems that her high-school best friend and crush Rebecca is back in Shannon's life, even if she-and no one else-can see her. Things seem perfect, until Rebecca wants to dig up the pains of the past-pains that Shannon would rather leave well enough alone. But in death, as in life, what Rebecca wants, Rebecca gets.Lucky for Rebecca, Shannon would kill for her.
