by Roderick Gordon And Brian Williams
Will Burrows is an ordinary boy with an unusual obsession: digging. When his father mysteriously vanishes into a forgotten subterranean passage, Will follows him into the dark and discovers the Colony, a sprawling, brutal society hidden deep beneath the earth. This series is not for the faint of heart. It is relentlessly claustrophobic, trading the open sky for damp stone and the crushing weight of miles of rock. The pacing is frantic, mirroring Will's desperate survival as he peels back layers of conspiracy and realizes that the surface world is merely a fragile shell covering something much more ancient and hostile. If you enjoy stories that feel physically restrictive and favor grit over wonder, this will grip you. It is perfect for readers who prefer their adventures laced with paranoia and the genuine fear of being buried alive.
Since you finished the series and are likely still feeling the urge to explore, we have curated these titles because they share that specific, unsettling fascination with what lies hidden beneath our feet. Whether you are looking for the political dread found in Uglies and The Golden Compass, or the visceral, horror-tinged exploration seen in The Descent and Subterranean, these picks center on the same claustrophobic tension. These authors understand that the most terrifying secrets are the ones buried directly under our own homes, waiting to be unearthed by someone curious enough to start digging.

Like Tunnels, this novel features a subterranean society struggling with decaying infrastructure and a desperate need to uncover the truth about their world. It captures that same sense of claustrophobic exploration and the feeling of being trapped in a dying, hidden civilization.
For readers who enjoyed the scientific and adventurous aspects of exploring the Earth's depths, this thriller offers a more adult, high-stakes journey into a vast, hidden underworld. It mirrors the intense pacing and the discovery of ancient, dangerous secrets beneath the surface.
This series shares the core premise of a boy discovering a massive, dangerous civilization beneath his own feet. It balances the wonder of discovering a new world with the grim reality of political conflict and survival found in the Tunnels series.
Both series feature young protagonists thrust into a mysterious, confined environment where survival is the only priority and the truth is hidden by layers of conspiracy. The sense of isolation and the need to decipher the rules of their prison will feel very familiar to Tunnels fans.
