Plot
Mickey7 is an Expendable, a disposable employee on a human expedition to colonize the ice world Niflheim. His job involves undertaking the most dangerous missions, with the understanding that after each death, a new clone will be created with most of his memories intact. After six deaths, Mickey7 is well aware of the terms of his employment and the reasons behind his acceptance of this unenviable position.
During a routine scouting mission, Mickey7 goes missing and is presumed dead. However, he manages to return to the colony base with the unexpected assistance of native life-forms. Upon his return, Mickey7 discovers that a new clone, Mickey8, has already been created to replace him. Faced with the universal loathing of duplicate Expendables and the risk of being recycled for protein, Mickey7 must keep his double a secret from the rest of the colony.
As Mickey7 grapples with his predicament, life on Niflheim deteriorates rapidly. The colony faces numerous challenges, including an unsuitable atmosphere, food shortages, and unsuccessful terraforming efforts. Adding to these problems, the native species begin to show increasing curiosity about their new neighbors, causing great concern for Commander Marshall.
The situation becomes even more complex when Commander Marshall believes that the colony's creeper neighbors possess an antimatter bomb. Mickey7 finds himself in a pivotal role, as Marshall considers him the only one capable of preventing the creepers from using the weapon. As tensions rise and resources dwindle, Mickey7 realizes that the survival of both human and alien life forms may ultimately depend on his actions and decisions.
