The Demon King (A Seven Realms Novel) by Cinda Williams Chima, I read all three books in this series, lots of twist and turns. Good read. http://www.amazon.com/dp/1423121368/ref=cm_sw_r_pi_dp_LPgsrb1896DS3
The Girl of Fire and Thorns series by Rae Carson. Don't let this pic fool you, it's a trilogy, the three on the bottom are just novella's. I am in LOVE with this series!!!! One of the best fantasy series I have read in a long time, absolutely amazing!!!!
