"One of the few laugh-out-loud novels I've read." --Conan O'Brien

Lamar Jimmerson is the leader of the Gnomon Society, the international fraternal order dedicated to preserving the arcane wisdom of the lost city of Atlantis. Stationed in France in 1917, Jimmerson comes across a little book crammed with Atlantean puzzles, Egyptian riddles, and extended alchemical metaphors. It's the Codex Pappus: the sacred Gnomon text. Soon he is basking in the lore of lost Atlantis, convinced that his mission on Earth is to administer to and extend the ranks of the noble brotherhood.

Charles Portis wrote five novels, and this is his penultimate. Portis is often compared to Mark Twain because, like Twain, Portis focuses on and plays with the wide range of expression found in American speech. Every character in this novel has a unique way of expressing himself, and it's clear to the reader that Portis genuinely loves each and every one of these characters and creating for them a unique vernacular.

For fans of True Grit or other Charles Portis novels and for readers who have yet to discover his work, a trip with Portis and Lamar Jimmerson will be great fun and full of rewards.

"A wonderful talent--original, quirky, exciting." --Larry McMurtry, author of The Last Picture Show and Terms of Endearment

"I've loved his work all my life--The Dog of the South is a family favorite, as is Masters of Atlantis. . . . The books are so funny that they cry to be read aloud." --Donna Tartt, author of The Goldfinch and The Secret History, in the New York Times
