"First published in the United States as an e-book by Farrar, Straus and Giroux"--Title page verso.

"It is August 1969. Young Ajax Penumbra has arrived in San Francisco, the capital of counterculture, seeking neither psychedelic deliverance nor a fortune made in silicon. He is searching for a book, the single remaining copy of the Techne Tycheon, an ancient and mysterious volume reputed to have occult power. His quest is full of dispiriting dead ends -- but when he stumbles across a 24-hour bookstore, the possibilities before him expand exponentially."--Back cover.
