After her father’s disappearance, headstrong healer Rhianwyn finds herself in a perilous position. The king’s law forbids unwed women living alone, but she neither needs nor wants the numerous men vying for her hand. The explosive chemistry between her and mysterious Lord Broccan tempts her to bed—but not to wed. So, when Broccan receives royal permission to marry her, Rhianwyn is furious.
Her friends Elspeth, Selena, and Lilliana envy her fate, which seems better than that of servant, harlot or bartered princess. At the mystical sunstones where they meet to bemoan their powerless futures, a crone appears, offering them a magical opportunity to swap souls for a season. With each believing any life is better than the one given her, they agree, beginning a journey that will change them, their friendships, and their destinies forever.
Broccan, however, didn’t bargain on loving a wife who changes with the seasons. As Rhianwyn starts seeing her independence—and Broccan—through new eyes, she realizes that the pact meant to free her may destroy her best chance at happiness.
