A book is a product of a pact with the Devil that inverts the Faustian contract, he'd told Allie. Dr Faustus sacrificed eternity in return for two dozen years of power; the writer agrees to the ruination of his life, and gains (but only if he's lucky) maybe not eternity, but posterity, at least. Either way (this was Jumpy's point) it's the Devil who wins.
