From Adrian Tchaikovsky, the acclaimed, award-winning author of Children of Time, comes an unparalleled narrative of alien contact and human discovery in this follow-up to Children of Ruin.

Mickey7 is the mission Expendable. A disposable member of the crew whose job is to tackle life-threatening and suicidal missions, a new clone being made after each death. On a frozen world with hostile lifeforms, Mickey7's real trouble starts when he's mistaken for dead, and a new clone is activated. There's only one thing worse than being an Expendable, and that's being a duplicate.
