The Heart Breaker (Rocky Mountain 2) by Nicole Jordan

Burdened by family debts, Heather Ashford has no choice but to exchange her dreams of romance and accept the proposal of ruggedly handsome cattle baron Sloan McCord. However the widowed rancher is more than she bargains for.

Sloan McCord has vowed never to love again. Although his infant daughter needs a mother, he doesn't want--or need--a wife. He is surprised that Heather, an elegant city-bred lady, turns his remote Colorado ranch house into a home, and tenderly cares for his child. She is beginning to haunt his thoughts by day and steal his breath by night--and this he cannot have if he is to keep a safe distance. Does his fierce bride of convenience have the strength to heal his broken heart--before he breaks hers?
