When an Antarctic research expedition goes wrong, the consequences are far-reaching - for the men involved and for their families back home. Robert "Doc" Wright, a veteran of Antarctic field work, holds the clues to what happened, but he is no longer able to communicate them. A stunning novel that tenderly unravels different notions of heroism through the rippling effects of one extraordinary expedition on an ordinary family. From the Booker Prize-longlisted author of "Reservoir 13".
