It feels like this book was written in a hurry to wrap up a series that probably could have had more life in it. 
 It's a supernatural story with barely any supernatural action, in fact barely any action of any kind. I so badly wanted something to happen. 
 *Reminding myself not to read this again because the only interesting part is the not-very-twisty "twist" in the end, and once you know what happens there's no other point to the book.
