I Am Her Revenge

She can be anyone you want her to be.
Vivian was raised with one purpose in life: to exact revenge on behalf of her mother. Manipulative and cruel, Mother has deprived Vivian not only of a childhood, but of an original identity. With an endless arsenal of enticing personalities at her disposal, Vivian is a veritable weapon of deception.
 
And she can destroy anyone.
When it’s time to strike, she enrolls in a boarding school on the English moors, where she will zero in on her target: sweet and innocent Ben, the son of the man who broke Mother’s heart twenty years ago.
 
Anyone…except for the woman who created her.
With every secret she uncovers, Vivian comes one step closer to learning who she really is. But the more she learns about herself, the more dangerous this cat and mouse game becomes. Because Mother will stop at nothing to make sure the truth dies with her.
