The Dark Twin. The murdered girl who has been in Allie's head for as long as she can remember. She knows things, and she's the reason no foster families have ever wanted to keep Allie. But things are set to change when Eva and John Cranwell come to meet her, and she is welcomed into the family with her three new foster sisters. It might be too good to be true. Allie has just moved to the town where the Dark Twin lived and was brutally murdered. Now that the killer knows Allie is there, it's only a matter of time before they come after her, especially once they learn about the connection.
