"Mickey7 is an "Expendable"--a disposable employee on a human expedition sent to colonize the ice world Niflheim. Whenever there’s a mission that’s too dangerous―even suicidal―the crew turns to Mickey. After one iteration dies, a new body is regenerated with most of his memories intact. On a routine scouting mission, Mickey7 goes missing and is presumed dead. By the time he returns to the colony base, his fate has been sealed. There’s a new clone, Mickey8, reporting for Expendable duties. The idea of duplicate Expendables is universally loathed, and if caught, they face being recycled into protein to feed a hungry colony. Meanwhile, life on Niflheim is getting worse, and the native species are growing curious about their new neighbors, which has Commander Marshall very afraid. Ultimately, the survival of both lifeforms will come down to Mickey7. That is, if he can just keep from dying for good" -- Provided by publisher.
