Her Witch, Her Demon (Book 1 of Hers Trilogy)

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.

Unraveling 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.
