The highly anticipated new novel from the Costa-award winning, three-times Booker-longlisted author of Reservoir 13.

Doc Wright could be two steps or two miles from his team. In an ice storm, distance loses meaning. No one can see. No one answers their radio. All he can do is keep going, but something has gone wrong inside his head.

Back home, he is the only one who can explain what happened to them in Antarctica. But after what changed on the ice, everything has lost its meaning. Now his wife, Anna, must become his carer. Now he must find a new way to be in the world. All he can do is try to tell his story – even if words fail him.
