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.

High school is tough enough without bringing in extra complications. Quentin Robinson has managed to keep secrets from his family, friends, and even his girlfriend, but his world is about to change. Earth is in the crosshairs of a homicidal alien race from another galaxy. Infiltrators have been here for years quietly moving the pieces into place. Only one thing stands in their way--a small group of aliens from a competing civilization. The good guys have a plan to stop the invaders, but they need help to implement it. It's the kind of help that no one on Earth should be able to give; the kind that Quentin just happens to be able to provide. It's a race against time. It's a race across time. Can Quentin and his newfound friends make it in time?
