No, it's not going to be happening anytime soon. It's a sequel idea bouncing around that won't be started until after I finish writing several centuries down the timeline, and there really isn't much of a plot built yet besides zombies in space. The only thing I have for it right now is a tentative title: "Haunted Sky"
