I really enjoyed this one - think it was my fave out of all of this series. I like that there were several on going games which all intertwined 

I said this on my review of book 2 and ill say it again, i did enjoy the audio and is easy to follow and the story often recaps prev clues/answers so you know exactly what the characters know and how they got to that conclusion. My only issue is that there are so many moving parts and so much information that i kinda wish i had eyeball read it just so i can flick through and actually look at everything that happened
