Finally,  the presidential summer reading list is revealed — well, one book anyway.

OBAMA/President Barack Obama took his daughters book browsing on Day 2 of the First Family’s summer vacation on the upscale Massachusetts island of Martha’s Vineyard.

Obama, casually dressed and sporting a baseball cup of his beloved White Sox, greeted and shook the hands of surprised shoppers in The Bunch of Grapes book store on Main Street in the pretty seaside town of Vineyard Haven, before leading Sasha, 9, and Malia, 12, upstairs to browse.

The First Reader bought Freedom by Jonathan Franzen, a novel that The New York Times review said showcases “his ability to throw open a big, Updikean picture window on American middle-class life.”

A sales assistant said the  president also purchased “To Kill a Mockingbird,” Harper Lee’s Pulitzer Prize winning classic tale of racial tension in the segregated south of 1930′s America, and John Steinbeck’s “The Red Pony,” set on a California ranch in the same era. (We’re thinking those books were probably for the girls).
