Colette deEstaing has adored Gaston, the son of her father's master of horse, since they were both children. Now grown, she must wed an aristocratic friend of her noble father's. When her fiancé assaults her in the stable, a savage stallion comes to her aid and kills the dissolute marquis. That's when she learns Gaston has inherited the ancient gift of shape-shifting into equine form. Shocked and fearful, she urges him to flee before he is accused of murder or witchcraft. But first she must convince him to take her virginity in one magical night of love.
