I read this book in a couple of days. It wasn't the most exciting book I've ever read, but I still enjoyed it. Although the main character went a little farther than what is probably bound to happen in a real life situation, I think it is a fairly believable idea for someone to be curious about the person their significant other is possibly cheating on them with. I suppose for some people the book could be a bit dry, but for me, I was pulled into the story fairly quickly and couldn't seem to want to stop reading until the end.
