I stumbled onto this book, not knowing it was the last of a series of 3. I kept wondering where this book was leading me, and I'm so glad I stuck with the journey. It's definitely fiction, but I enjoyed reading about the questions/choices the main character grappled with and I loved the doesn't-whack-you-in-the-head ending. This is one of those times reading that I'm glad I let my curiosity get the best of me. I'm not sure after reading this one that I'm up for going back and reading the other two "out of order" -- I wish I had attempted them in order, but I'm glad that I read this one.
