This summer the Penderwick sisters have a wonderful surprise: a holiday on the grounds of a beautiful estate called Arundel. But the best discovery of all is Jeffrey Tifton, son of Arundel’s owner, who quickly proves to be the perfect companion for their adventures. The icy-hearted Mrs. Tifton is not as pleased with the Penderwicks as Jeffrey is, though, and warns the new friends to stay out of trouble. One thing’s for sure: It will be a summer the Penderwicks will never forget. Written by Jeanne Birdsall, this book was first published in June 2005 and won a National Book Award plus four other awards that same year. It’s 272 pages and available in hardcover.
