Black Sun is a 1971 novel by Edward Abbey about a fire lookout who falls in love with an American girl and is wrongly blamed when she mysteriously disappears in the Grand Canyon National Park.

He lived in a trailer behind the entrance cabin, but he was absent so often that he demonstrated that we did not need a lookout, because having Abner in the tower was the same as having no one.

Because Judy had spent some time with Abbey when he worked as a fire ranger, some readers naturally believe the book is based on their relationship.

He reported on March 17, 1968, that Judy hated it, 'thinking it the story of one of my old love affairs, which in a way it is, but only in a greatly altered and much exaggerated way.

The novel is about a rugged fire lookout, Will Gatlin, who falls in love with an American girl half his age and then becomes wrongly blamed when she mysteriously disappears in the nearby Grand Canyon National Park.
