The Bounty Hunter’s Sister by Jovie Grace

Charity Powers isn’t aware of her late husband’s debts, and she certainly isn’t trying to dodge payments when she and her four-year-old daughter board a train. They arrive in the cozy small town of Cedar Falls, Texas, to attend her brother’s wedding.
The moment Schmidt Barnes tracks her down, he realizes something more sinister is afoot. Unfortunately, his lovely target can’t afford a lawyer to defend her, and she’s way too proud to accept money from family or friends.
He can think of only one other way to provide the round-the-clock protection she and her daughter need — by marrying her. All that’s left is convincing the stubborn beauty that exchanging vows with a rugged bounty hunter is truly her best option.
