Long Live the Queen — Kate Locke

Xandra Vardan thought life would be simpler when she accepted the goblin crown and became their queen, but life has only become more complicated. Everyone -- vampires, werewolves and humans -- wants the goblins on their side, because whoever has the goblins -- wins.

Queen Victoria wants her head, Alpha wolf Vex wants her heart, and she still doesn't know the identity of the person who wanted her blood. What she does know is that a project from one of the 'secret' aristocrat labs has gotten free and she's the only one who can stop the perfect killing machine -- a sixteen year-old girl. With human zealots intent on ridding the world of anyone with plagued blood and supernatural politics taking Britain to the verge of civil war, Xandra's finding out that being queen isn't all it's cracked up to be, and if she doesn't do something fast, hers will be the shortest reign in history.
