Five sons of an English duke, all raised in the Rocky Mountains... When a Montana blizzard strands two strangers in a cave, honor demands a vow neither of them want. Nobody knows the truth about newly knighted Lord Thomas Balfour. He doesn't deserve the being honor showered on him, so after this last trip with his brother and sister-in-law to Butte for supplies, he'll leave this territory behind completely. But once he reaches town, he's blindsided to discover his brothers have ordered him a bride by post. A woman complicates everything. And even worse-the bride has brought her sister. Kate McKinney masterminded this journey west to rescue her younger sister from their controlling mother's plans. Yet one look at the intended groom's scowl, and Kate's doubts bloom. Maybe this mail-order marriage scheme will be far worse for her beloved sister than the wealthy brute their ambitious mother arranged. Thomas has no choice but to help escort the sisters back to the Balfour ranch. On the trail, a blizzard changes everything, tearing Thomas and Kate away from the others-straight into danger...
