When I started this book, I didn't think I'd enjoy it since I'd already seen the movie. Boy, was I wrong! Dennis Lehane's mystery is very psychological drama and goes far deeper into the characters than the movie could. I was amazed by Lehane's ability to dig into the minds of his characters, and his ability to write interior dialog. Mystic River is a taught, compelling thriller, and I can't wait to read more of his books.
