Desperate to prove herself to her crew of space mercenaries, engineer Caro Ogunyemi takes on a solo mission to infiltrate the top secret human experimentation laboratory run in a secret prison by the deadly Pierce family that rules her corner of the galaxy.

Caro realizes she really messed up right about the time Carmichael Pierce injects a bomb into her neck to control her. If that wasn't enough, all her engineering skills seem to be backfiring as a residual alien infection crashes the machinery in everything she touches.

As she works her way deeper into the laboratory, Caro meets their star subject: Leviathan, a super soldier turned mindless killing machine by a chip in his head...until Caro touches him. The same alien infection jamming her datapad and ruining her life also breaks the control chip turning Leviathan into Pierce's puppet.

In the heart of enemy territory, Caro and Leviathan must figure out how to escape and recover his agency before Caro's alien infection heals and Leviathan is lost to her forever.
