Hearts at Stake by Alyxandra Harvey

Lucy's best friend Solange Drake is going to become a vampire. And soon. She'll turn on her sixteenth birthday, or die. Vampires are coming out of the woodwork, wanting to be close to her, kill her, or just kidnap her.

Solange knows there's a prophecy saying she'll be a vampire queen. She's the first female vampire to be born--the rest have been created. But everything is happening too fast.

Before they know it, they're hunted by other vampires and vampire hunters, all with varying motives. The only people Solange can rely on are Lucy and her family, and strangely, one of the vampire hunters Kiernan. But she'd rather save them than the other way around.

Told from Lucy and Solange's points of view. Both have love interests (of course) and both fight for their existence. Lucy and Nicholas (one of Solange's brothers) take the stage towards the end as they race to save Solange before it's too late. Romance, action, and more vampire lore. Good thing I can't get enough of it!

Fire by Kristin Cashore

In the Dells, a kingdom is on the brink of civil war. King Nash inherited his father's mess--his father's only aim to please his close friend Cansrel, a human monster who could control thoughts and lived to see others suffer.

Cansrel's daughter, Fire, shares his abilities, but not his taste for suffering. She has hidden away her entire life to avoid controlling people, invading their thoughts, and being hunted. But the King calls on her to help avoid losing his kingdom, and she can't refuse the chance to undo the terror her father thrived on.

Just as fascinating as Graceling, Fire involves drama, action, adventure, and romance. There are many elements at play here, and it seems Fire is the focus in most of them, just as Katsa was. Her bravery and courage turn out to be her greatest assets.
