Can a secret be kept forever?Five years ago, Shannon Astor left the beautiful high-mountain country of West Texas as a single mother. She was desperate for a fresh start and a way to keep the secrets of her past buried. It almost worked. Until a chance to make a better life for her daughter leads her right back home. To the very place of the past betrayals. But it also leads Shannon to horse-trainer Jack MacGowan--her handsome high-school nemesis, now a widowed father. His daughter looks so startlingly like her own that Shannon can't help but question the circumstances surrounding her daughter's birth. Wary of each other's intentions, Shannon and Jack reluctantly join forces to untangle a deep mystery that swirls around Shannon's parents, a lost Spanish treasure, and a legendary black stallion. If Shannon can learn to entrust her secrets to the man falling in love with her, the truth just might set her free.
