"A new era of cosmic adventure begins - with the Guardians caught between the Collector and the Grandmaster! And that's bad news when Groot can't grow any bigger than baby-sized, Drax has sworn off violence, and Gamora is hiding something! Can the gang get it together before they find themselves in the middle of a war between the Nova Corps and the shadowy Fraternity of Raptors? Hydra's Secret Empire brings the Guardians back to Earth - but who will blast back off with them as their newest member? And the hunt for the Infinity Stones begins - a search that involves our ragtag renegades becoming ... Novas?! But no Infinity quest can be complete without Adam Warlock!"--Amazon.
