Deep Six — Ian Thomas Healy

When criminals are convicted, they go to jail. When they have parahuman abilities, they go to Deep Six, the most secure prison facility in the world. Six thousand feet underground, nobody has ever escaped from the maximum security facility. Until now. A parahuman terrorist called Misrule engineers a mass breakout, and it falls to a pair of prison guards to stop the world's most dangerous criminals from reaching freedom, and Just Cause won't be able to help them. Despite being overmatched and underpowered, the two guards must find a way to prevent the escapees from their ultimate goal.
