I absolutely loved the parts of this that I read. It was on the back of the Can in the master so I occasionally picked it up and opened it to a random spot and read for anywhere between 2 and 15 minutes.
From what I gather What I gather the body snatcher takes control of the Melanie and then melanie becomes her own conscience and then there is some kind of love triangle that happens with melanie, the body snatcher, and Jared. Even though the body snatcher is in complete denial.
If I was Stephanie Meyer's Husband I would be seriously concerned with how obsessed she is with love triangles...I would also worry that she wasn't really my wife at all!
I could be totally off, but skimming the book this is my take!
