I love Ellen Hopkins. She is a phenomenal writer. I have read almost all of her books (except Tricks) and I can't get enough of them. They are so sad and beautifully illustrated that I really feel the pain of each of her characters.
My favorite would have to be Burned followed closely by Impulse and Identical. I always cry when I read Burned. Always. I've read it at least a dozen times and it still touches me. I really understand how the main character feels.
Whats your favorite book by this truly inspiring author?
