Pretending to Be Erica

Erica Silverman was abducted when she was four.  She was snatched outside her kindergarten and never seen again.  Over the past thirteen years, her multimillionaire parents have spared no expense trying to find her. 
Then, one day, the miracle happens.  Erica frees herself from her kidnappers and finds her way home. 
She is seventeen.  Years of her life are lost. She is battered. She has PTSD.  She has to relearn everything about who she is and where she's from. 
And there's one more thing:  She is not Erica Silverman. 
Violet is the daughter of the best con man in Las Vegas.  She has spent her whole life preparing to step into the shoes of a girl she has never met. 
But she is also Violet, and she has a job: stay long enough to steal the legendary Silverman Painting.  Walking a razor's edge, calculating every decision, not sure sometimes who she is or what she is doing it all for, Violet is getting lost in her own lies. . . .
