Desperate to give her twin daughters a decent life, Julie Fulton agrees to marry Grady Hawks and produce the son he needs to inherit Hawks Nest ranch. At the end of a year, child or not, Julie will receive enough money to escape to San Francisco and leave behind her rough existence.
Grady intends to breed back to the fair skin and Scottish features of his father and Julie meets every requirement. Her red hair and pale skin are an excellent way to dilute Grady's half Kiowa blood. If Julie breeds true, their child will prove that the Hawks family is "white" enough to own Texas land.
The formula is right, but the outcome unexpected. Siring a son is the last thing on Grady's mind when he discovers pleasure in Julie's bed. And San Francisco no longer seems like paradise to Julie when she finds heaven in Grady's arms.
