Her Black Magic by A.J. Norris

Freya is a villain, blaming herself for her father’s sins. Despite everyone telling her she was also his victim, she can’t quite wash the blood from her hands. She turns to black magic for protection from the negativity and evil spirits surrounding her life. However, her spells are weak against the power of the poisoned amulet in her possession. Her soul is in danger of damnation. Even worse, she wants nothing to do with the angel sent to save her. She’s sworn off all men and convinced the gorgeous angel she just met is an ordinary guy even though the kiss they shared was heavenly. Desperate to get rid of him, she tries banishing him, but he won’t go away.
Joelle can’t forgive himself for causing the fall of his best friend. For decades he’s carried around this shame. Plagued by guilt, Joelle keeps messing up. He’s sent to save a woman from ending up in Netherworld but all he does is make her angry. And if that’s not bad enough, the strikingly beautiful Freya doesn’t believe he’s an angel. Yet, bound by duty he can’t leave her alone until she gives up the amulet or accepts what he is before it’s too late to save her soul.
