Earthbound

Quentin hasn't had much time to rest since saving the world just a week ago. Every night, he goes back in time to train and plan the capture of dangerous agents from the Hwanai. His skills are improving, but their plans have hit a snag, and new information discovered about Quentin leaves the team wondering if there is more to this teen than they ever considered. With new enemies as well as old foes threatening Earth and all of us on it, one thing is clear. The danger has doubled! There's a surprise around every corner, it seems, and nothing could prepare Quentin for what's about to happen.
