Casandra Hilton, a New York debutant and East Coast heiress is found floating on a bed of seaweed and wood wreckage off the coast of South America. But when asked for her name or any kind of identification, she responds with a blank stare. Even though she has survived, she has no memory of her former life and any attempt she makes to remember fills her with fear. The kind Uruguayan family that took her in soon becomes dependent on her innate abilities with horses, particularly one troublesome stallion. Shane Stapley, a Texas billionaire, has traveled to Argentina to purchase a champion stallion from the Cortez ranch. Early one morning he finds Casandra dealing with a stallion who refuses to leave the stables where they keep the mares. Everything about her draws him closer until he learns she cannot guarantee her heart is free to fall in love. The attraction is obvious, but the risk is great. Will their patience pay off in a match between them or end in sorrow when they learn they must part?
