Hunt on Dark Waters

Evelyn is a witch with a weakness for theft, bad decisions and danger, and when she robs her vampire ex and flees through a portal, she tumbles into Threshold, a magical sea between worlds. She is pulled from the water by pirates, the Cŵn Annwn, sworn to guard the portals and hunt the monsters that slip through, and their telekinetic captain Bowen gives her a choice: join the crew or die. Bowen has no memory of his past and no room for distraction, but the attraction between them burns hotter as danger rises, and Evelyn has no intention of keeping her vows. The first Crimson Sails book is a spicy pirate fantasy romance drawing on Welsh mythology; reviewers praised its world-building and heat.
