A Trail so Lonesome by Lacy Williams

Spending five months eating trail dust wasn’t Leo Spencer’s first choice. Or his second. He’s not one to run away, but some situations can’t be fixed and his family—two brothers and a sister—needs to start over. Which is how he finds himself on a westbound wagon train. Evangeline has a secret, one that has sent her on a journey across the plains on the Oregon Trail. When her father is badly hurt and she needs help, Leo is there. A deal is struck and the two unlikely friends form an alliance… that leads to more. But Evangeline’s secret looms over her… and Leo’s family troubles are far from over.
