A Bride for the Cowboy by Linda Goodnight

He’s desperate for redemption.

Rancher Ace Caldwell can’t change the past, but he can try to make amends. His battle with alcohol paralyzed a good friend—and cost Ace the woman he loved. But Ace’s determination to do the right thing falters in the face of Marisa’s mistrust and Chance’s apathy.
She’s one bounced check away from losing everything.
Once upon a time, Marisa Foreman believed in true love, and in the charming cowboy who seemed larger-than-life. Then her brother’s accident shattered her illusions and her trust in the cowboy. Working two jobs just to stay afloat and as Chance’s primary caretaker, she has no time for romance. And even if she could forgive Ace, how could she ever trust him again?
But Ace sees what Marisa can’t, and it isn’t long before they clash over what’s best for Chance. When Ace’s steady presence starts to creep past Marisa’s defenses, she must face what she fears most. Can Ace’s love overcome the mistakes of his past?
