In a domed city on a planet orbiting Barnard's Star, a recently hired maintenance man named Kane has just committed murder.
Minutes later, the airlocks on the neighbourhood block are opened and the murderer is asphyxiated along with thirty-one innocent residents.
Jax, the lowly dome operator on duty at the time, is accused of mass homicide and faced with a mound of impossible evidence against him.
His only ally is Runstom, the rogue police officer charged with transporting him to a secure off-world facility. The pair must risk everything to prove Jax didn’t commit the atrocity and uncover the truth before they both wind up dead.
