Bob13 Challenge: Your favorite BoB13 read

Today I've decided (/figured out that I'm able...) to participate in another challenge. Once Upon a Chapter has a picture challenge where you find your favorite book in this bout of books so far.

This was surprisingly hard because on one hand I'm currently reading The Lions of Al-Rassan by Guy Gavriel Kay and I'm really enjoying it, on the other hand I really loved How to Build a Girl by Caitlin Moran, which is the book that comes victorious out of this simply because I know how it ends. Who knows, maybe Lions will fall apart completely in the last 150 pages? (I don't thinks so, but I don't know for sure).
