One evening, a young woman saunters in and, between mouthfuls of chips, invites him to visit her in the World of Ideas. Ben is excited, but suspicious. The World of Ideas is the philosopher's quarter of the afterlife, and adorable Lila has been residing there for thirty years, but being dead is just the start of her problems.
