Shadows on Society Hill: An Addy Mystery (American Girl Beforever Mysteries)

In the winter of 1866, Addy's poppa gets a new job, and his employer, Mr. Radisson, offers the Walkers a home of their own on the grounds of his fine house in Society Hill. Addy's delight quickly evaporates as she realizes that Mr. Radisson's house holds frightening secrets--one of which leads straight back to the plantation where Addy's family was held in slavery only two years before.
