Anne has stumbled upon an incredible discovery from Aunt Edie’s private historical book collection: an antique map of Pennsylvania with evidence that it could have been used by Lewis and Clark! Is the map legitimate, and if so, how did Aunt Edie manage to come across such a valuable artifact? Meanwhile, Anne’s son, Ben, has been acting odd as of late; he leaves home for extended periods of time, but always immediately comes home when Anne calls him. What is he hiding? Find out in Shadows of the Past, the exciting second book in the Secrets of the Blue Hill Library series!
