Heart at Stake (The Drake Chronicles, 1) by Alyxandria Harvey, 2010.
I'll make this really quick. I've been putting off starting Hearts at Stake for a couple of months now (I was afraid it be like HoN which I didn't like). But I finally decided to bite the bullet and just start it, and it has more then exceeded my expectations and I'm only on page 84. Can't wait to finish it (and the other books in the series).
