Query: An uncomfortable but good read

The dog attack ripped me apart (no pun intended). It was hard for me to get beyond that scene, but I eventually did. Though this was a dark and somewhat melodramatic work, with characters that at times were hard to relate to, I found that I couldn't put it down, even though I wanted to. Oh, how I wanted to.The story did wander--sometimes aimlessly, and it did make me uncomfortable at times, but there was a sense of hope for an ending that might have some semblance of happiness. I suppose I was foolish to wish for that. The overwhelming sense of sadness was something I'd not experienced while reading a book, and yet, I can honestly say that despite how uncomfortable it made me, in the end I was glad to have read it.
