Girls Can't Be Knights

Portland has a ghost problem.
Sixteen-year-old Claire wants her father back. His death left her only memories and an empty locket. After six difficult years in foster care, her vocabulary no longer includes "hope" and "trust."
Everything changes when Justin rides his magical horse into her path and takes her under his wing. Like the rest of the elite men who serve as Spirit Knights, he hunts restless ghosts that devour the living.
When an evil spirit threatens Claire's life, she'll need Justin's help to survive. And how could she bear the Knights' mark on her soul? Everybody knows Girls Can't Be Knights.
