In Her Skin by Kim Savage

Jo is homeless, living on the streets of Boston. She left home when her mother was killed by her latest boyfriend. Jo's and her mom were con-artists. Jo's mom taught her all about choosing your make, being someone else and playing people to separate them from their money. Life has never been that great. 

One day, Jo sees the opportunity to escape to a new life. She will become Vivienne Weir, a girl who went missing nine years ago. Since Vivienne's parents died, Jo will be taken in by the Lovecrafts, the neighbors who were watching Vivi when she disappeared. They live in a luxurious house. They have a daughter, Temple, who was Vivi's best friend. It is all more than Jo could ever have dreamed. 

Sometimes becoming Vivi is too easy for Jo. Everyone wants Vivi back so much that they overlook obvious contradictions (like does Jo really look like an older version of Vivi?). Only the police seem skeptical. But the intervention of the police social worker and the powerful influence of the Lovecrafts override any doubts. 

Jo can never really relax. She wants to be loved by Temple, but her new 'sister' has a darker side. The whole family doesn't seem to quite fit making for a lot of tension. It is also a long con to play. Jo can never be Jo again, but she's ultimately not Vivi either. And now that she's in, can she get out?

With a little suspension of disbelief, you can enjoy Jo's suspenseful excursion into a life she has never experienced. With nothing feeling quite right, there is no time to relax in the pages of the book. But it is worth it.
