Intriguing concept, but the whole book just moved so slowly. I still can't believe the whole thing takes place in only one week. The characters were interesting, and I enjoyed some of their internal dialogues, though a lot of it seemed petty. The plot became pretty predictable about a fourth of the way through the book, and that was disappointing. I wanted to be more surprised. 
 I will say that I listened to the audio book, and I thoroughly enjoyed the narrator's Australian accent. It's had me thinking with an accent the past few days.
