This isn't my usual taste (as I read Stephen King and other disturbing novels) but I picked it up because I read the reviews and they made it sound good, and well, it is. Very good. It also made me cry, alot, especially with her brother Ed and all the problems her Mother faces.
The writing is simple, yet flows beautifully, and sucks you straight into the story.
Really really nice story, and one that stays with you long after reading it. I highly recommend it, and it's good for children and adults alike (I'm 21)
