Guardians of the Galaxy by Gerry Duggan (Omnibus)
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, 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!
