“Are you happy with your life?” Those are the last words Jason Dessen hears before the masked abductor knocks him unconscious. Before he awakens to find himself strapped to a gurney, surrounded by strangers in hazmat suits. In this world he’s woken up to, Jason’s life is not the one he knows. His wife is not his wife. His son was never born. And Jason is not an ordinary college physics professor, but a celebrated genius who has achieved something remarkable. Is it this world or the other that’s the dream? And even if the home he remembers is real, how can Jason possibly make it back to the family he loves? The answers lie in a journey more wondrous and horrifying than anything he could’ve imagined—one that will force him to confront the darkest parts of himself even as he battles a terrifying, seemingly unbeatable foe. In a review in The Guardian, Alison Flood described Dark Matter as one of "the most helter-skelter, race-to-the-finish-line thriller you'll read all year".

In December 2020, it was announced that a TV series based on Dark Matter will be co-produced by Apple Studios and Sony Pictures Television.
