Massachusetts ? In the first full day of a Martha’s Vineyard vacation, President Barack Obama set aside some of the cares of office Friday to work on his family’s summer reading list.

Obama emerged from the Bunch of Grapes bookstore carrying a brown paper bag and preceded by Sasha, 9, and Malia, 12, who’s rejoined the family after her first summer camp.

Inside the bag was “Freedom” by Jonathan Franzen, aides reported. The novel portrays a family of urban homesteaders in St. Paul, Minn., who decamp to the nation’s capital. It’s not on sale yet, but the store gave him an advance copy. The president also purchased “Tinkers” by Paul Harding and “A Few Corrections” by Brad Leithauser, the bookstore said.

For the girls, the president bought two volumes: “To Kill a Mockingbird” by Harper Lee and “The Red Pony” by John Steinbeck, a cashier said.
