by Russell Hoban
An inexplicable message flashed onto the screen of his Apple II computer at 3am heralds the beginning of a startling quest for frustrated author Herman Orff. Taking up the offer of a cure for writer's block plunges him into a semi-dreamland inhabited by a bizarre combination of characters from myth and reality; the talking head of Orpheus, the young girl of Vermeer's famous portrait, and a frequency of Medusas.
