The Gone World by Tom Sweterlitsch is a science fiction thriller steeped in horror, one that quietly steals hours from you before you realize you’ve been holding your breath for most of them. I would know, I finished it in two days.
The novel plunges the reader straight into devastation: an apocalyptic version of our world set in 2199, marked by reverse crucifixions and an endless looping forest that feels alive with menace. It is disorienting, brutal, and unforgettable. From this nightmare, we are introduced to Shannon Moss, a Naval Criminal Investigative Service (NCIS) agent who is deeply complicated, intelligent, and compelling – a character perfectly suited to a story that obscures your sense of reality.
The Gone World begins, at its surface, as a murder and missing persons investigation. A family has been brutally killed; their daughter is missing; and the father, who was once a Navy SEAL, has vanished. As Shannon digs deeper, she discovers that the missing man was involved in a top-secret Naval Space Command program, one of the first to board a spacecraft designed to travel into future versions of the world. But the ship never returned, and the crew was presumed long dead. Yet within the remains of his dead family lies the evidence of his continued existence. How is he alive? What happened to the rest of the crew? Where is the spaceship? What happened to his family? Where is his missing daughter?
To find answers, Shannon will travel through space and time, stepping into the terrifying unknown. She journeys to Inadmissible Future Trajectories (IFTs), alternate future timelines that exist only as possibilities. The moment she returns to her own time in 1997, the IFT ceases to exist.

As the story moves between multiple IFTs, we encounter different versions of the same characters, people shaped by choices they have not yet made, and may never make. The effect is profoundly disorienting, both for the reader and for Shannon herself. Relationships form and vanish, and Shannon remembers it all. When the narrative snaps back to 1997, the emotional whiplash is unavoidable, leaving quiet grief for lives unlived.
What begins as a crime investigation gradually entangles itself with something far more terrifying: the end of the world. Through its exploration of future timelines, the Navy has uncovered an inevitable extinction event known as the Terminus. Each journey into the future confirms it. Worse still, the Terminus appears to be drawing closer to the present, becoming increasingly inescapable.
This is what makes The Gone World so haunting. The novel is steeped in strangeness. Its scientific explanations are cinematic yet destabilizing, grounding the impossible in just enough logic to make it feel real. It is not a hopeful book, though it pretends to be. Hope flickers, only to be extinguished again and again. By the end, the reader is left wondering not just whether the world can be saved, but whether it should be.
Deeply unsettling, relentlessly suspenseful, and strangely beautiful, The Gone World is a story that lingers long after its final page, like a future you’ve seen but can never return to.
