Query: Excellent book

This beautifully written book allows the reader to know these characters from the inside. Their thoughts, emotions, and inner dialog are explored in an unsentimental and clear way. You can't read this book without facing a few dark corners in your own psyche, which is probably a big reason for the wildly varying reviews contained in this website. It's an intimate journey, one which I found well worth the time.
