Silhouette Desire, book like New.
He could tame any wild mustang—but no woman had come close to taming Rand Blackhawk. Yet one lady spitfire dared enter the arena with the tantalizing Texas maverick. Socialite Grace Sullivan desperately needed Rand's expertise, but she didn't figure her pleas to save a herd of horses would lead to a world of sensual self-discovery in Rand's strong arms. He branded her as his own, taking her virginity one powerful night and searing her guarded soul. But when their mission ended, would Grace be forced to release her untamable Blackhawk...or could she hold her unbridled lover forever?
