Another Freebie. This time a sample of books at Beth Revis' site:
I've read Nightshade, Matched, and have "Across The Universe" in my TBR pile so if that is any indication, Born Wicked and Legend should be great! If you don't have these already, I'd say run and get the free samples.
Not sure if people in outside the US can get it (hello, CP#1).
