Gift Idea: An Unexpected Book

Surprise me! Is there anything better than getting a book you never knew you wanted, something, maybe that you've never even heard of? Or maybe just a book that you'd always meant to read but never got around to, something that was on your to-read list, taking up room at the bottom of the list like that fan you brought with you to college and never used. So this year, get me something I never could've guessed was coming.
