I feel somewhat guilty that I decided how I'd rate the book around chapter four because I was sure the story did not include (view spoiler)[a rekindled love affair between Olivia and Jack (hide spoiler)]. Lucky for me, the story did not include that plot point so I enjoyed it -- a lot, so have many stars! This is definitely my favorite novel by Burke, and I think it may very well be her best novel of those that I've read. I was guessing up until the very last chapters and I found the ending very satisfying. Olivia is a great character and narrator--very flawed in her development but I think that makes her interesting, and I'd love to see her show up again. 
 The sum-up: Flawed woman being awesome and competent, or Burke doing her thing.
