The Raven Curse by Emilia Hartley

Ciaran wouldn’t ask a Carver witch for help even to keep himself out of Hell. After all, he’s managed to live a full century with the curse a Carver put on him. But now, a demon is chasing him, and the magic residing in his curse could literally unleash Hell on Earth. Ciaran needs a Carver to undo the curse and stop a catastrophe. But when he seeks out this generation’s Carver witch, he discovers he wants her to do much more with him than just lift a curse.
All her life, Samantha Carver has heard tales of the dangerous murderer her great-grandmother cursed, so it’s no wonder that when the man shows up in her yard, she tries to shoo him away. But the unsettlingly sexy man won’t go, and the more Samantha gets to know him, the more she questions what she’s always heard.
Is the simmering attraction Ciaran and Samantha share enough to overcome a hundred years of distrust and misunderstanding?
Or is their relationship—and Samantha’s sleepy town—doomed?
