Emeralds in the attic
(Book)

Annie Dawson and her friends in the Hook and Needle club are preparing for the social event of the year, a masquerade ball hosted by the Stony Point Historical Society. Searching the expansive attic of Grey Gables to find gowns and accessories for the ball, they discover an antique set of faux-emerald jewelry. The set is the perfect complement to Annie's own gown, but little does she know where the discovery will lead her and her friends.
