Severed Signals - Vincent Chen, #1

The enemy of my enemy. Vincent Chen keeps star systems in close communication with each other as he tends to the comms ferry satellites that connect the Realm of Five. When he responds to small colony's apparent malfunction, though, he stumbles onto an enslaved people. The problem is, the enslaved used to be the oppressors. They're all former agents of Kesek, the secret police that spent the last century suppressing religion by arresting, torturing, and killing believers-including Vincent's uncle.
But it also includes the children and families of those agents. Vincent is drawn deeper into the plot against them, until he's forced to choose the right side.Whether he can forgive, however, is the most dangerous question.
