On Track for Treasure by Nikki Loftin
Book two in a historically rooted series that's The Boxcar Children for a new era! When the town sheriff discovers the exact location of Wanderville, the orphans who live there Jack, Frances, Harold, Alexander, and their new friends must flee their home in the woods. They take to the rails and, after nearly being caught, are rescued by a seemingly kind reverend and his wife. The pair brings the children to their home, telling them that if they help the sharecroppers who run their farm, they will eventually be adopted. But Frances can t stop thinking about a mysterious treasure mentioned to her by a hobo they met during their travels, and when a young African-American sharecropper is blamed for stealing a fiddle her brother Harold actually nabbed, the citizens of Wanderville will have to decide whether their community is heading in the right direction or whether they need to get their town back on track."
