The Threadmender Chronicles - House of Blight: 1 by Maxym M. Martineau

A dark and spicy enemies-to-lovers fantasy romance about a beautiful healer mage forced out of hiding and into service of a charismatic but aloof fae lord after her brothers contract a deadly plague.

Perfect for readers of Jennifer Armentrout, Suzanne Wright and C. S. Pacat.

Edira Brillwyn has a secret. Edira Brillwyn is a threadmender.

She holds a rare, lifesaving power that can cure disease and heal injuries in the blink of an eye. But magic always comes with a cost and saving anyone sacrifices a sliver of her own life. Edira's beloved aunt Rowena - a fellow threadmender - taught her to conceal this ability to protect herself from people who would take advantage, especially their powerful and wealthy neighbors.

Withholding her magic will save her life. Orin Fernglove is immortal - an everliving - and head of the prominent Fernglove house. The Ferngloves own the local mines, possess magic powerful enough to alter the stars, and don't take "no" for an answer.
