Armchair fiction presents extra-large paperback editions of the best in classic science fiction novels. Rex Stout’s “Under the Andes” is the ninth installment of our "Lost World-Lost Race Classics" series. It features grand adventure with a large helping of the mysterious. When three daring American adventurers decided to go mountain limbing in Peru they had no idea what was in store for them. They soon found themselves standing in front of the entrance to a mysterious cave—a cave from which no one had ever returned. Upon entering, they plunged into an underground river, which carried them deep underneath the mighty Andes mountains. Soon they were afoot in the realm of a lost race of Incas. But what the intentions of this deformed race of half-blind savages were toward their pale-skinned visitors—friendly or hostile—was anyone’s guess.
