When Franny and her older sister, Valentine, are summoned by their aunt Theodora from foggy San Francisco to sunny New York City for one summer, they are taken to timeless locales like Bemelmans Bar and the Sherry-Netherland and instructed on how to be a lady by their chaperone, Clover, Aunt Theodora's protégé. Franny is thrilled by all of the sophisticated outings, but Valentine has more pressing concerns. Boys! As they wander around New York City going lingerie shopping and learning about the simple elegance of a cucumber sandwich, they unearth secrets about Aunt Theo's romantic past and even have a few romantic adventures of their own, in Charlotte Silver's The Summer Invitation.
