Collects Nova (2013) #23-27. AXIS tie-in! It's a perfect jumping-on point when Sam Alexander, the newest Nova, faces...wait, is that the Hulk? What happened to him? Find out why they're fighting — and more important, just how Sam thinks he has a chance! Then, Carnage ensues when the psychotic Cletus Kasady comes to Carefree! Carnage knows Nova's secret identity — and he can't wait to share it with Sam's whole school! What's worse, Nova's helmet is still on the fritz! When's this kid gonna catch a break? Not today, when a Hulk makes an unexpected reappearance!
