What does Vivian store in her attic in the novel, Orphan Train?

Vivian stores her past in the attic - boxes of mementos, papers, documents, souvenirs, and possessions that define both who she was and who she became. Molly's work clearing out the attic is representative of Vivian's attempts, throughout the narrative, to organize and understand her past, and also Molly's simultaneous attempts to work through the difficulties associated with her own history.
