Guardians of the Galaxy by Donny Cates.

Donny Cates’ complete Guardians saga in one stellar volume! Hundreds of worlds are at war. More than ever, the galaxy needs the Guardians — but in the aftermath of the Infinity Wars, who is left to answer the call? Thanos is dead, but the search for his successor has just begun. Who will it be? And who are the Dark Guardians? Cosmic chaos commences when the new Guardians take on Thanos’ Black Order — but could the Mad Titan be fighting his way back from the grave?! Plus: The Universal Church of Truth returns at the worst possible time — because Rocket Raccoon is dying! He’s still got some fight left in him, but his allies are few and the odds are slim. Can Rocket hold on long enough to make a difference?
