Doomed (Ancient Legends #2)by Jayde Scott
I didn't realize when I put this on that it was Book #2, although it looks like they could stand alone as well. Book 1: A Job From Hell, is $0.99
Marked (Book 1)by P. C. Cast and Kristin Cast
I've read most of these and really liked them.
Evermore (Book 1) by Alyson Noel
I've also read most of this series, and liked it as well.
