Bestselling authors Margaret Atwood and David Sedaris have been added to the long list of celebrity authors appearing at Lisner Auditorium in the fall.

Sedaris, the popular humor author of “When You Are Engulfed in Flames,” “Dress Your Family in Corduroy and Denim,” and “Me Talk Pretty One Day,” will speak Oct. 7 at 8 p.m. His appearances in Lisner are a regular fall favorite. Atwood, known for her novels “The Handmaid’s Tale” and “The Blind Assassin,” will speak Oct. 30 at 8 p.m.

At the Atwood event, the writer will conduct a dramatic reading from her newest novel, “The Year of the Flood,” with the help of several students, according to the Lisner Web site.

Joining Sedaris and Atwood at Lisner in the fall is Pulitzer Prize-winning author Michael Chabon, who will speak Oct. 9 at 8 p.m. Chabon read at GW last year, as part of an English class designed to introduce students to prominent Jewish-American authors.

Former Vice President Al Gore will read from his new book, “Our Choice,” on Nov. 5. No ticket information has been released for the Chabon or Gore readings, and both events are being held in conjunction with Politics and Prose Bookstore.

Student tickets for the Sedaris event start at $15, and it will cost $10 to see Atwood. The Lisner Box Office is Tuesday through Friday, 11a.m. to 5p.m. and accepts cash, GWorld, MasterCard and Visa.
