The Marriage Barter (Orphan Train, #2)

Mission: Children Rounding up a gaggle of orphans isn't Wyatt Reed's specialty. Still, the bounty hunter is being paid handsomely to bring these children from Evans Grove to the next town. And then he sets eyes on one pigtailed, pint-sized complication, and the beautiful widow who needs his help. 

Charlotte Miller's marriage lacked love, but at least it gave her the right to adopt little Sasha. Now without a husband, she can't be a mother. Wyatt agrees to be her groom-for-hire-only until Sasha is hers. But the man who couldn't wait to leave town is finding unexpected reasons to stay...and glimpsing a future surpassing any fortune he's known.
