Fourth Galaxy, 4 November 2052: in the blackness of space a figure in blue overalls tumbles over and over as it drifts towards the planet Badr-al-Budur. No space suit, no helmet, no oxygen. He can't be alive, can he? But he is.

First Navigator Fremder Gorn is the only survivor when the Corporation tanker Clever Daughter disappears. Nobody knows how he did it, and everybody, including Fremder himself, wants to know. Dr Caroline Lovecraft, Head of the Physio/Psycho unit, finds that intimacy doesn't lead to answers and Fremder's own memories are resolutely obscure. Fremder's name means stranger, and his story is otherworldly and yet ultimately life-affirming.
