Vineyard author Ward Just’s latest novel is among President Obama’s reading choices for his summer vacation on the Island.

In addition to purchasing several books for his daughters Friday during a visit to Bunch of Grapes bookstore in Vineyard Haven, the President bought two books for himself: The Bayou Trilogy, a collection of three short noir novels by Daniel Woodrell; and Rodin’s Debutante, Mr. Just’s coming-of-age novel set in Chicago where he grew up, the White House said.

Mr. Woodrell is best known for his novel Winter’s Bone, on which an Oscar-nominated film was based.

On his first full day of vacation, the President followed a book shopping trip accompanied by his daughters with a long afternoon of golf and dinner with his wife, Michelle, at the Beach Plum Inn in Menemsha.

The Obamas, who arrived on the Island Thursday afternoon, stayed out of sight at Blue Heron Farm on Friday and Saturday mornings. On Friday afternoon, the President headed for the Vineyard Golf Course in Edgartown where he spent the afternoon on the private course.

Chicago friend Eric Whitaker, White House trip director Marvin Nicholson and senior advance lead Michael Brush rounded out the foursome.

On Saturday, the White House released the names of the two books that the President bought for himself, but did not report what titles his daughters, Sasha and Malia, had purchased.

Mr. Obama also brought along three additional books: Cutting for Stone, a novel by Abraham Verghese; To the End of the Land, a novel by David Grossman; and The Warmth of Other Suns, the story of America’s Great Migration, by Isabel Wilkerson.

Ms. Wilkerson and Mr. Just discussed their books earlier this month at the Martha’s Vineyard Book Festival.

Mr. Just, a longtime West Tisbury resident, had a distinguished career in journalism and is the author of more than a dozen novels.
