The sequel of Fallen Angel - due in early 2012. Stay tuned.
I have just finished reading your book, Fallen Angel, and it was amazing. I just fell in love with the characters and the storyline was so interesting. It kept me guessing until the very end and even then I never guessed who the killer was. I just loved it and I can't wait until the next book comes out.
