Heirs to a great dynasty, the Delaney brothers were united by blood, united by devotion to their rugged land ... and known far and wide as THE SHAMROCK TRINITY. Powerful men... rakes and charmers... they needed only love to make their lives complete.

Rafe Delaney was a heartbreaker whose ebony eyes held laughing devils and whose lilting voice could charm any lady -- or any horse -- until a stallion named Diablo left him in the dust. It took Maggie O'Riley to work her magic on the impossible horse...and on his bold owner. No woman had jolted Rafe Delaney's heart until this tiny dynamo had come to Shamrock Ranch; now her grace and strength made him yearn to share the raw beauty of his land, to teach her the exquisite pleasure of yielding to the heat inside her. Maggie was stirred by Rafe's passion, but would his reputation and her ambition keep their kindred spirits apart?
