The fast-paced New York Times bestselling thriller of the year from Blake Crouch, author of the bestselling Wayward Pines trilogy.

'The most helter-skelter, race-to-the-finish-line thriller you'll read all year'
Guardian

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.'

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. Something impossible.

Is it this world or the other that's the dream? The answer lies in a journey more wondrous and horrifying than anything Jason could've imagined. One that will force him to confront the darkest parts of himself if he is to ever return to the family he loves and the world he calls home . . .

Crouch keeps the pace swift and the twists exciting. Readers who liked his Wayward Pines trilogy will probably devour this speculative thriller in one sitting [as will] those who enjoy roller-coaster reads in the vein of Harlan Coben
