Dark Matter is a mindbending, relentlessly surprising thriller from Blake Crouch, author of the bestselling Wayward Pines trilogy. "Are you happy with your life?" Those are the last words Jason Dessen hears before the masked abductor knocks him unconscious. Jason awakens to find himself strapped to a gurney, surrounded by strangers in hazmat suits. A man he's never met smiles down at him and says, "Welcome back, my friend."

In the world he's woken up to, Jason's life is not as he knows it. His wife is not his wife. His son was never born. He's not an ordinary college physics professor but a celebrated genius who has achieved something remarkable—something impossible. Is this world or the other the dream? And even if the home he remembers is real, how can Jason possibly make it back to the family he loves?

The journey that lies ahead of Jason is more wondrous and horrifying than anything he could have imagined—one that will force him to confront the darkest parts of himself even as he battles a terrifying, seemingly unbeatable foe. Dark Matter is a brilliantly plotted tale that is at once sweeping and intimate, mind-bendingly strange, and profoundly human—a science-fiction thriller about choices, paths not taken, and the lengths we'll go to claim the lives we dream of.
