Callisto's Ghost

Shen took the long way home to Jupiter's moons. He got lost in a dark world of slavery for years and it left scars on his soul. In earning his freedom, he picked up an assortment skills useful in certain parts of society and became a ghost in the machine. Shen gave his loyalty to those who showed him kindness and now he has to take on his toughest job yet to keep them safe: breaking into the powerful surveillance corporation that's already looking for him. Lena cut a deal with that same corporation to escape court-ordered mental reprogramming. The deal brought her out to Jupiter's Callisto colony and put her to work tracking ghosts, but no hacker fits into cubicle life well. As she's chafing under the terms, she's handed a new hunt: someone who's been eluding them for years. But he's worth more to her as an escape from slavery - if they both survive.
