Somebody's coming

California: Twelve-year-old Melanie has been in foster care her whole life, moving from home to home--unloved and unwanted. And although she has found relative contentment with her current foster parents, Melanie harbors a secret that, if discovered, would blow her world apart. Someone talks to Melanie, a presence no one else can see or hear, and this presence has a message for her: something bad is about to happen.

New York: After years of battling with her troubled, unpredictable mother, Louise has managed to find peace in her solitary existence. Until the day Grace crashes back into her life and entreats Louise to help her save a child from imminent danger. Unwilling to get caught up in her mother's madness, Louise resists. But she realizes the only way to be rid of Grace once and for all is to play along.

Louise and Grace set off across America in search of Melanie, driven by Grace's firm belief that they have to get there before the bad thing happens. To do that, Louise must first come to understand and trust her mother. But after a lifetime of pain and dysfunction, can the two finally heal old wounds in order to save one young girl?
