I am reading A Feast for Crows by George R.R. Martin. It is not a YA book, but it is a very good series. It started with Game of Thrones (perhaps you have heard of the HBO program), the first in the Song of Fire and Ice series. It is very good. I am thoroughly enjoying it. It is also very long, over 1000 pages. So, I am plugging away.
My next YA book will probably be Passion by Lauren Kate. Third book in the Fallen series.
Happy reading all!
