Amy O'Brien vows to do anything in her power to keep a shady relative from obtaining custody of her newly-orphaned niece and nephew-and control of the sizeable trust fund left to them. Enter Wyoming rancher Reese Cavanaugh, the children's only other relative, with an offer Amy can't refuse: if he and Amy were married to one another they would almost certainly be granted custody of the children. Aware that this may be the only way to protect her niece and nephew, Amy accepts Reese's offer-after making sure he understands that this marriage will be strictly a business arrangement. What neither of them counted on, in this seemingly foolproof plan, was falling on love.
