John Crowley (born December 1, 1942 in Presque Isle, Maine) is an American author of fantasy, science fiction and mainstream fiction. He studied at Indiana University and has a second career as a documentary film writer. He is best known as the author of Little, Big (1981), which received the World Fantasy Award for Best Novel.

In its recent review of the fourth (and final) Ægypt novel, Bookforum said: "We may one day look on Ægypt's publishing history with the same head-scratching curiosity with which we now regard Melville's tragic struggles and André Gide's decision to turn down Swann's Way." As those words were being typed, Overlook was well into the process of reclaiming the magnificent tetralogy, and with the publication of The Solitudes, readers re-entered the fantastic world that enthralled reviewers and was enshrined in Harold Bloom's Western Canon.

In Love & Sleep, the second volume of the series, the professor Pierce Moffett finds himself at a great turning point in the history of the world. As a child, Pierce was no stranger to magic, but those revelations faded with time. Now Pierce's search for a secret history of the world--one in which magic works and angels speak to humankind--has begun again. Love & Sleep is a modern masterpiece, both extraordinary and literary.

Love & Sleep will be followed in Summer 2008 by the third volume in the Ægypt cycle, Dæmonomania, and in Fall 2008 by the paperback release of book four, Endless Things.
