Train to Somewhere — Eve Bunting

Marianne, heading west with fourteen other children on an Orphan Train, is sure her mother will show up at one of the stations along the way. When her mother left Marianne at the orphanage, hadn't she promised she'd come for her after making a new life in the West? Stop after stop goes by, and there's no sign of her mother in the crowds that come to look over the children. No one shows any interest in adopting shy, plain Marianne, either. But that's all right: She has to be free for her mother to claim her. Then the train pulls into its final stop, a town called Somewhere . . .
