Heartmate by Robin D. Owens
Danith Mallow is irresistibly drawn to the magnificent necklace on display in T'Ash's shop, but she is wary of its creator, despite an overpowering attraction. In a world where everyone is defined by their psychic ability, Danith has little, placing her at the opposite end of the social spectrum from T'Ash. But T'Ash refuses to accept her rejection and sees it as a challenge instead. They are HeartMates, but can T'Ash persuade his beloved to accept her destiny by his side?
