Furia has always been an outcast, looked down upon by her kind due to the dark mark her parents' legacy has left on her. Taking her in as an infant after her parents' death, her uncle has refused to allow her to train to be a demon slayer like everyone else. Now she has turned of age and must choose a life: to become by some miracle a demon slayer or to let her shadow take over and send her into the shadow realm. Her only hope is the other orphan her uncle had taken in, James, but can he teach her twelve years of training before her 21st birthday when she must make her choice? Or is she doomed to become a shadow? See how the story begins in the first book of the short story series Shadows.
