By far this has been my favourite book in the series. 
 I know I said I wasn't going to continue with Harper and Tolliver's story but this book was on special and I couldn't help myself. I'm glad I couldn't. 
 The brother/sister thing didn't bother me so much in this one because Harper stopped referring to them as that. I was actually rather glad at the developments in their relationship. 
 I always feel glad when I can solve the mystery before the characters and this was no exception. Despite knowing that, I liked how the story played out and I'll definitely be reading the 4th book as soon I get my hands on a copy.
