Court of the Undying Seasons

Fin is nineteen and living in a village that must send young people to the Finding. When the call comes for the person she secretly loves, she volunteers in that person's place. She is taken to Castle Courtsheart, a school for human students who are trained to become vampires.

The stakes at Courtsheart are fixed. A student who succeeds is turned into a vampire. One who fails becomes a thrall, and some do not survive the training at all. Fin has come with a private aim: to learn how the undead can be killed and to avenge her mother, who was taken by vampires years ago.

The castle proves as seductive as it is dangerous, and Fin is soon pulled into its life. She is drawn most of all toward Gavron, the vampire assigned as her maker. He is hostile toward her and magnetic all the same, and the pull between them grows as she changes and discovers a new power in herself.

Then Fin finds a string of murders among the school's people. They may be linked to a much larger and deadly ritual. She has to identify the killer before the cost reaches everything she has, her heart included.

This is a dark fantasy with a vampire romance at its center and a murder mystery running through it. The castle setting gives it a gothic, charged mood, with danger and attraction sharing each scene.
