Dark Moons Rising — Nia Farrell

Deidra of Ravenhill is a daughter of light, a healer whose energy can be tapped by the one who marks her. Mordred, bastard son of Owain ap Coel, is determined to be that man. He's captured the castle, killed her family, and forced her to train as a comforter, preparing her for his ultimate possession. While Mordred is gone, having the brand made to claim her, Deidra manages to escape the castle. She nearly dies in the forest but is saved from falling into a poacher's pit by Thorne, a dark lord, one of the race of giant shifters that she's been taught to fear since childhood. With dark moons due to rise on the most dangerous night of the year, Thorne must become a centaur for them to escape the monsters that roam with the god of chaos. He carries her to the safety of his brother's hunting lodge, but is she truly out of danger? From Mordred, perhaps, but there are two dark lords who want her - if she's willing to share.
