Book excerpt: "In this searching biography of the writer’s imagination, Mary Gaitskill excavates her own novels, revealing their origins and obsessions, the personal and societal pressures that formed them, and the life story hidden between their pages. Using the techniques of collage, The Devil's Treasure splices fiction together with commentary and personal history, and with the fairy tale that gives the book its title, about a little girl who ventures into Hell through a suburban trapdoor." -- Publisher's website.
