I did a little research and it looks like there are quite a few different covers for this book, but my library happens to have the most copycat-ish of them all. I've heard about (and seen) this happening with stock photography for smaller YA fiction titles before, but sharing the cover of a Printz and National Book Award winner? Wowzers.
Update: I did a little searching to see if anyone else had caught this copycat, and sure enough, someone did! Kudos to She Reads and Reads for seeing this first (though her copy cover shows one of the alternate covers, "She" catches yet ANOTHER similar cover as well!).
