If you're a fan of dystopians (teen or otherwise) you need to read these.

I featured Matched in its own Pre-Pub post here. As always, you can read my review at Bookbitch.com in the review archives--I lurved it completely!
Warning, I'm posting the synopsis of Crossed now and it does have spoilers if you haven't read Matched:
