He swore he'd never marry. She swore she'd never surrender her heart. But when honor and desire collide, every promise is put to the test. Duke is a powerful, ruggedly handsome cowboy billionaire with a reputation as untamable as the Wyoming land he owns. Proud, dominant, and guided by an unshakable code of honor, he has no intention of settling down-until a desperate young woman shows up on his doorstep, begging for help. Kim's world shattered the day she became the guardian of her two little siblings. To protect them from their dangerous father, she needs Duke's influence and power. But the price of saving her family is higher than she ever imagined: a marriage of convenience to the man who makes her pulse race and her defenses crumble. What begins as a business-like arrangement soon turns into something neither can fight-a scorching attraction that blurs the lines between duty and desire. But as passion ignites, so do the threats against them. Someone will do anything to tear them apart... even if it means taking Kim away forever. Bound by honor. Torn by desire. Will love be enough to save them?
