UNDER THEIR SKINS, by Margaret Peterson Haddix

The story: (Spoiler alert!) Nick and Eryn are just two middle school kids...until the day they find out that their parents are robots, and that the entire human race has gone extinct except for a few kids now growing up under the care of androids. As they search for the cause of the extinction, a mysterious message in a cave leads them to realize they can't trust anybody--not even the "people" they've always called their parents.

Liz's comments: Haddix does a great job of ratcheting up the suspense as the kids try to figure out what their parents are hiding. A cliff-hanger ending is pretty much taken for granted, but rumor is that this is a 2-part series, which is almost as good as a stand-alone. :)
