Beyond the Veil Publisher's Summary
"They say I'm half demon, but I like to think of myself as half human, especially as the demons want me dead."
Charlie Henderson is living a lie. Her real name is Muse and her attempt at a normal life is about to go up in smoke. When a half-demon assassin walks into her life, leaving a trail of destruction in his wake, Muse must return to the one man she hoped never to see again and ask for help. The Prince of Greed isn't known for his charity. The price is high, but the cost could tear her apart.
Trapped between the malevolent intentions of a Prince of Hell, an assassin with ulterior motives, and her bloodthirsty demon-kin, Muse must embrace the lure of chaos at her core; the demon inside her, in order to survive. When your ex is the Prince of Greed, you'd better be ready to raise hell.
