This was definitely my least favorite book of the series. The ending, in particular, was so stupid. Cassie's mom did not have to die at all. It felt so pointless. Reminded me of The Mist ending. Like all they had to do was wait a tiny bit, and she would have been fine. The part where Dean held Cassie and told her loved her was cute, though. It felt like 75% of the book was just a whole lot of nothing and then all this randomness at the end. Idk not my fave. But I'm glad I finished all the main books.
