Query: Depressing!

Good grief! Could there be anything more depressing than this book? I would have quit reading about 1/3 of the way through, but I just kept thinking it would get better. It didn't. You couldn't even like the characters. They were all so plagued with problems- guilt, anguish. I had heard high praise for this book, but now I'm left wondering why?
