Behind Closed Doors by B.A. Paris

I just loved this book. It was hard to get through, but once I got through I couldn't stop thinking about the characters. Quite unusual for me, as I usually read in bed and usually couldn't tell you the plot of a book I read a month before. There are two books that have stuck with me - Behind Closed Doors, and The Darkest Evening of the Year by Dean Koontz.
