Lost and alone.
Stranded in a galaxy far from home, with no way to call for help, engineering officer Cassi Requin and her crew of survivors are pursued by a hostile spacecraft. As food and supplies run low, they make a desperate decision to descend to the surface of an unforgiving planet to extract the raw materials they need for repair and replenishment.
But lurking in the shadows lies a relentless enemy Cassi has confronted before—a hive mind sentience that's out for blood.
As conditions on the surface diminish, an allegiance on her spacecraft crumbles, forcing her to fight on a new front.
With leadership lost and threats on all sides, Cassi must draw on every skill she has, assume command, and lead her crew home.
