All That Earthly Remains

"All That Earthly Remains" by C. C. MacApp is a science fiction novel written during the early 1960s. The book intriguingly explores themes surrounding ancient civilizations, the intersection of science and spirituality, and impending disaster, as a group of characters navigates the aftermath of a mysterious nuclear explosion in a remote Andean region. The story centers around Dr. Luis Craig, a nuclear physicist, who is called to investigate the explosion that has uncovered ancient tunnels and is believed to possibly connect to extraterrestrial forces. The narrative follows Dr. Craig as he joins a diverse group, including a priest, a general, and an indigenous guide, embarking on an expedition to the explosion site. As they delve deeper into the tunnels, they encounter a glowing, intelligent entity that reveals connections to both biblical tales and potentially destructive technology.
