Hunt on Dark Waters

A witch named Evelyn, drawn to danger and known for her light fingers, steals from her vampire ex and tumbles through a portal into another realm. She is pulled from the waters by a seafaring crew led by a telekinetic captain and forced to choose between joining them or dying. The captain, Bowen, has no memory of his life before becoming one of the Cŵn Annwn, a group bound by vow to patrol Threshold, the magical sea between realms, and safeguard its portals. As attraction grows between the two, so does danger, complicated by Evelyn's own intentions regarding the vows she is expected to keep.
