The Faceless Woman (The Otherworld, #4) by Emma Hamm

Once upon a time…

A town will only suffer the presence of a witch for as long as she is useful. Aisling watches the flames lick her thighs and prays for a quick death. But when an Unseelie prince appears through the smoke, she does what any self respecting witch would do.

She curses him.

Bran should never have traveled to the human realm, and is shocked when a witch binds them together. His life is hers and he refuses to die. He saves her from the fires, casts a hex on the townsfolk for good measure, then whisks her away to safety. His only stipulation? She has to remove the binding curse.

Unfortunately for them both, she can’t. Witch and Unseelie must travel across the Otherworld to break the ties that bind them. Secrets and lies stand between them, but both will stop at nothing to save themselves.
