This is probably my favorite book in the series. I'm writing this review after finishing book 4, so I can confidently say it doesn't get better.

I felt like I was playing a game of Clue. I had so many suspects I had to write them down. Ending Spoiler, it's not who you think*

The cliff hanger on this book literally had me screaming and I almost chucked my phone across the room.

If at any point during the first two books you considered quitting, please don't. This is worth the read.
