Witches and demons have hated each other for thousands of years. At least that's what the young witch, Meredith Huang, has been told all her life. She's never met a demon, but the stark difference between demoncraft and witchcraft is enough to prove that demons are vile creatures who can't be trusted. Then Meredith meets the dashing Onyx Castle, a woman who makes her heart flutter for the first time. There's just one tiny problem: Onyx is a demon. Unravelling their growing feelings for each other is the easy part. Together, they must overcome enemies who will do anything to tear them apart, figuratively and literally.
