A Confederacy of Dunces
One of the BBC's '100 Novels That Shaped Our World' 'My favourite book of all time... it stays with you long after you have read it - for your whole life, in fact' Billy Connolly A monument to sloth, rant and contempt, a behemoth of fat, flatulence and furious suspicion of anything modern - this is Ignatius J. Reilly of New Orleans, noble crusader against a world of dunces. The ordinary folk of New Orleans seem to think he is unhinged. Ignatius ignores them, heaving his vast bulk through the city's fleshpots in a noble crusade against vice, modernity and ignorance. But his momma has a nasty surprise in store for him: Ignatius must get a job. Undaunted, he uses his new-found employment to further his mission - and now he has a pirate costume and a hot-dog cart to do it with... Never published during his lifetime, John Kennedy Toole's hilarious satire, A Confederacy of Dunces is a Don Quixote for the modern age, and this Penguin Modern Classics edition includes a foreword by Walker Percy. 'A pungent work of slapstick, satire and intellectual incongruities ... it is nothing less than a grand comic fugue' The New York Times

A Heartbreaking Work of Staggering Genius
"I think this book is kind of malleable. I've never really wanted to put it away and be done with it forever -- the second I first 'finished' it, I wanted to dig back in and change everything around. So I'm looking forward to getting back into the text, and straightening and focusing and deleting. Most of all, I'm thrilled that Vintage will be letting me include all the cool chase scenes, previously censored." -- Dave Eggers The literary sensation of the year, a book that redefines both family and narrative for the twenty-first century.

A Heartbreaking Work of Staggering Genius is an instant classic that will be read in paperback for decades to come.
