The U.N. Owen is adrift in interstellar space. With no lights, no life support, no help for ten trillion miles, it seems as though things can't get any worse. Then, they find a body.

Ten astronauts are woken from suspended animation to deal with a crisis on board their ship.

Selected from a crew of thousands, none of them knows any of the others: all they know is that one of their number is a murderer.

And until they work out who it is, none of them can go back to sleep.
