Thank you to Net Galley and St. Martin's Press for an e-arc of this title in exchange for my honest review. This was a roller coaster ride of a book. There were some portions I didn't care for, such as when Susannah kept thinking/talking about her previous husband. He just seemed creepy, which I guess is the point. The characters were well done, and although I could see some things coming, I had a sense of realizing I couldn't stop it, which is the mark of a good psychological thriller to me. I really enjoyed this book a great deal. I highly recommend it.
