Callisto's Ghost

Shen took the long way home to Jupiter's moons and it left him deeply broken. As he healed, he picked up certain skills and became a ghost in the machine. Now Shen faces his toughest job yet: breaking into the powerful surveillance corporation that’s already looking for him. Lena cut a deal with that corporation to escape court-ordered mental reprogramming. The deal brought her to Jupiter and put her to work tracking ghosts. As she's chafing under the expectations, orders come down: hunt someone who’s eluded them for years.
