I read this a while ago and then gave to my spouse as a present.
Here's what I wrote about it when I read it as a bookcrossing ring in June 2015:

Here as a ring. I wasn't sure what I'd think of this - in fact I signed up for it and then later saw it on the forum and decided not to sign up (forgetting that I already had). Very glad it found its way to me.
I found it very well written, and the length of time it took me to get through it is only indicative of how busy the end of school year can be (and I confess I read something else in the middle), and in no way indicative of my interest in the book.
The whole premise was intriguing, and although the various sections with different characters are a bit scattered, it's still a very good read.
