Beneath Scotland's surface, explorers confront hidden riches, ancient danger, and the cost of progress.
When a routine coal survey beneath Scotland's moors uncovers vast, hidden galleries and a sealed subterranean realm, a small, determined band of engineers and miners descends into darkness to confront whatever secrets lie below. Jules Verne turns the tools of nineteenth-century science into keys to an underworld of cavernous wonders, claustrophobic passages, and strange remnants of a lost life, blending nail-biting rescue suspense with reflections on industry, resource hunger, and human resilience. Rich in geological detail, atmospheric dread, and breathtaking discoveries, The Underground City is a page-turning descent that rewards curiosity while keeping its deepest mysteries tantalizingly out of reach.
