The Kept Man by Jami Attenberg
I enjoyed this book quite a bit. I was able to really connect to Jarvis,and it had a twist at the end that I didn't expect. And you know how I love books that aren't predictable.
It always shocks me when I read a novel that has a character I can relate to so well. It just goes to show, no matter how alone or unique you think you are, you're really not.
