Freida McFadden: The Housemaid (The Housemaid, Book 1)

Description

I try to ignore how Nina makes a mess just to watch me clean it up. How she tells strange lies about her own daughter. And how her husband Andrew seems more broken every day. But as I look into Andrew's handsome brown eyes, so full of pain, it's hard not to imagine what it would be like to live Nina's life. The walk-in closet, the fancy car, the perfect husband.
I only try on one of Nina's pristine white dresses once. Just to see what it's like. But she soon finds out... and by the time I realize my attic bedroom door only locks from the outside, it's far too late.
But I reassure myself: the Winchesters don't know who I really am.
They don't know what I'm capable of . . .
