French writer Anne Berest will present a lecture on “Family Fictions: The Postcard, Gabriële, and Writing True Novels” at Boston College on April 23 at 7 p.m. in Devlin Hall 110. Berest’s novel The Postcard was a national bestseller, a Library Journal, NPR, and TIME Best Book of the Year, and winner of the American Choix Goncourt Prize. Based on the author’s own family history, The Postcard is a moving saga of a family devastated by the Holocaust and partly restored through the power of storytelling. With her sister Claire Berest, she is the author of Gabriële, a critically acclaimed “true novel” based on the life of her great-grandmother Gabriële Buffet-Picabia, Marcel Duchamp’s lover and muse, a leader of the French Resistance, and an art critic. Berest’s lecture is presented by the BC Lowell Humanities Series and cosponsored by the Boston College Fiction Days Series. The event is free and open to the public, but registration is required.
