The Warder's Vampire [Warder's Series Book 4]
Serafina was born a dhampir. The offspring of a Warder and a Vampire. The first in centuries. She has no idea that an ancient spirit is plotting to take over her body and use it for a purpose she couldn't imagine. Franc has been a vampire since he was born. He has never been exposed to magic in this form, and being dragged into Realm, fighting with dragons and goblins is so far off his personal scale that he might have to consult a therapist after it is over. Together, they make Halloween a night to remember for all the Warders and the inhabitants of Realm.
