People of the Book by Geraldine Brooks
I was so eager to read this novel--it seemed like exactly the kind of thing I'd love--but I struggled to keep interested through the first half of the book. The second half picked up a lot, and I thought the ending was good--entertaining and suspenseful. It's possible that my expectations were too high, because it's well-written and has some very good historical parts. Anyway, I think I'd recommend it, if only to get some other people's reactions to it.
