The Veil — Tiffany Aaron

When the fate of Earth is in the hands of a half-breed demon, all Hell could break loose. Beltaine is half-demon, half-mortal and all badass. She doesn't answer to anyone, especially not an obnoxious, self-righteous warrior angel. After killing her father, she's never been interested in any kind of relationship that might tie her down. Unfortunately, circumstances are quickly spinning out of her control, and she might find herself forced to work with an angel who'd rather kill her than love her.
