The Creation of Eve by Leigh Anderson

She isn’t sure which is worse—not knowing who she is, or learning the truth.

After waking up naked and alone but with no memory of her past, the girl called Ann would rather not know what happened to her. The horrific scars covering her body tell a tale of terror she is sure she would rather forget forever. But to the doctors and benefactors overseeing her care, the possibly sordid details of her past are too enticing to ignore. She is forced to undergo a hypnosis session to unlock the secrets of her past.

But once that door is open, it is impossible to close.
The memories Ann recall are scant except for one—her name is Eve. And the man who inflicted the damage upon her body gave her that name. One at a time, the doors of Eve’s mind open, and she cannot help but walk through them, revealing horror after horror until she is no longer sure who the real monster is.
