Random House has announced that Truman Capote’s long-lost first novel will be published next month. The manuscript for Summer Crossing, which Capote wrote beginning in 1943, was found in 2004 in a box of the author’s papers put up for auction. “Set in New York just after World War II, Summer Crossing is the story of a young lighthearted socialite, Grady McNeil, whose parents leave her alone in their Manhattan penthouse for the summer while they travel to France to check on their war-torn villa.”
