Jason Dessen has been abducted. His life has been stolen. To get it back, he will go on a journey more wondrous and horrifying than anything he could have possibly imagined. Dark Matter is a relentlessly surprising alternate-universe sci-fi thriller from Blake Crouch.

‘Are you happy in your life?’

Those are the last words Jason Dessen hears before the masked abductor knocks him unconscious.

Before he awakes to find himself strapped to a gurney, surrounded by strangers in hazmat suits.

Before the man he’s never met smiles down at him and says, ‘Welcome back.’
