Dragon Glass — Kathryn M. Hearst

Lord of House Scorpio, Zale Argyris is a man who rules his people and his emotions. Few would guess that beneath his calm, cool exterior are wounds as deep as the ocean. After an encounter with a female dragon leaves him injured, he suspects the fates do in fact have a twisted sense of humor—the rogue dragon is his mate.Diagnosed with a terminal disease, Mericela Christou has lived on borrowed time since childhood. When a man washes up on her beach, she's caught between following doctor's orders and spending one night behaving like a normal woman—not that normal women rescue sexy, castaway billionaires.The tentative peace of the four dragon races is threatened when a new power rises…and Meri must decide between playing it safe or risking everything for her future—a future where she could lose more than her heart.
