Sam Alexander is a kid bound by the gravity of a small town -- and a father whose ridiculous, drunken fairy tales about a "Nova Corps" were just another heavy burden. But lucky for Sam, gravity soon won't even matter -- and those troubles will be a billion miles away. It's a boy, a helmet and an intergalactic legacy! As Sam trains with the Guardians of Galaxy's Gamora and Rocket Raccoon, the helmet leads Nova into intergalactic conflict that will affect the entire Marvel Universe!
