Hourglass (Evernight #3) - Claudia Gray

Bianca has found refuge again with the Black Cross, and she and Lucas work desperately to keep her secret. In this company, being a vampire is a death sentence, and the two of them live and train alongside the hunters without anyone noticing her increasing need for blood.

Even though she's with the boy she loves more than anyone else in the world, Bianca can't help worrying about the family and friends she left behind. Caught between three feuding worlds, it's starting to feel as though she'll never be entirely at peace again.

When another betrayal puts the lovers in mortal danger once more, they realise that all they truly have is each other. But with the secret of Bianca's birth taking hold, not even Lucas can help her win her toughest fight.
