Don't ask him about his next book, because like most writers, Dan Chaon is convinced it might suck. But if his previous work is any indication, it'll be big. His Among the Missing, a collection of short stories, was a finalist for the National Book Award in 2001. You Remind Me of Me, Chaon's morose first novel about four interconnected lives, also won praise from reviewers. Now, from his cluttered attic in Cleveland Heights, Chaon is churning out his second novel and another book of stories. He says you might not want to read either one. We say you probably do.
