Court of the Undying Seasons

I'm becoming what I always have been, deep inside. A blade.
When Fin takes her secret lover's place in the village's Finding, she's whisked away to Castle Courtsheart, a notorious vampire school, where human students either become powerful vampires or spend the rest of their lives as a lowly human. . . that's if they survive long enough.
But Fin has no intention of becoming a vampire - she intends to kill them. Fin is quickly swept up in her new world and its inhabitants - particularly Gavron, her handsome and hostile vampire maker, whose blood is nothing short of intoxicating.
As she uncovers a string of murders and a deadly ritual that threatens both vampires and humans. Now, Fin must find the killer before she loses her life or betrays her heart!
