Loved, loved, loved The Elegance of the Hedgehog by Muriel Barbery.
I fully admit that I picked it off the shelf because of the title. I was a teensy bit unsure of where the book was going in the beginning, but I fell into it fairly quickly. It's sweet and funny and unusual. The ending wallops you out of nowhere, which I always love.
I also love that the people who gave it bad reviews on Amazon almost universally mention that they found it pretentious. I found the pretension purposeful and intentionally hilarious - I guess we all read things differently.
Do you ever go to Amazon and read other people's reviews after you've finished a book? I try to never do it before I read something, because I like to come to it without any idea of what I'm getting into.
