Sam and Hannah, a husband-and-wife team of starship engineers, are dropped into a creaking, crumbling space station in the Outblack, then trapped by slithering lizard-folk and xenophobic colonists. Lost and abandoned, Sam and Hannah explore dark reaches while battling rogue robots and fragmenting technology. Then they discover a pod-world turned inside out-and in danger of spinning apart. As earthquakes worsen, fires rage, and Union Marines battle aliens and natives, Sam and Hannah fight to stay alive and stabilize the station . . . before it flies to pieces, taking them and everybody else with it . . .
