A freaky Friday read, and I mean that in two ways. One it being Friday and second had a little concept of The movie with same name.
Jacky loses her boyfriend to a girl who is less of what she is, or is it because she is too much of a good girl. After falling asleep she awakes to the next day in the shoes of her ex-boyfriends new girlfriend....literally. The ending has a great flip. I have a feeling it will be explained more in the novel.
