I've decided to take this one on, as I have two books upcoming that apply to this challenge. The Battle of the Prizes requires you to read three books: a Pulitzer Prize novel, a National Book Award novel, and then a novel that won both. I'm choosing Angle of Repose by Wallace Stegner (#82 on the list) for my Pulitzer book, The Adventures of Augie March by Saul Bellow (#81 on the list) for my National Book Award book, and I'm not quite sure yet what I'll do for my "double dipper". Maybe E. Annie Proulx's The Shipping News. Wish me luck!
