Meryl Streep’s voice will be heard on a special project this summer: the first audiobook edition of the late Nora Ephron’s “Heartburn”. Random House Audio announced Friday that Streep will narrate Ephron’s autobiographical novel based on her marriage to journalist Carl Bernstein, first published in 1983. The Oscar-winning actress starred in the film version, which came out three years later. Streep was a close friend of Ephron, who died last year. They worked on several movies together. The audiobook is scheduled for July. Audio editions are planned for other Ephron books, including the essay collections “Wallflower at the Orgy” and “Crazy Salad.” The narrators haven’t been chosen. Many thanks to Glenn and Frank for the heads-up.
