This was a very short novella, less than 200 pages. I thought it was going to be more of a thriller than it was. However, I guess it would still be kind of scary for someone to come into your life and do what Simone did to Tracy. However, Tracy, nor the reader really didn't know how far Simone had gone with her "copycat" business until the very end. I think had everyone known a lot sooner, then it would have been more of a thriller. For me, this was just meh. Thanks to Grand Central Publishing for approving my request and to Net Galley for providing me with a free e-galley in exchange for an honest review.
