This second volume finds Peter Quill and the gang getting their bacons saved by someone who is more than a man, named Ego, who claims to be Peter's father. Despite skepticism due to Ego's seeming abandonment, Peter is invited to join Ego on the latter's own Eden-like planet, called, of course, Ego's Planet, where he must periodically return to in order to keep it alive, residing there with only his assistant, an empath named Mantis. Meanwhile, there's an powerful golden-skinned race called The Sovereign out to retrieve some stolen and highly valuable batteries from Rocket Raccoon, a fleet of Ravagers is on the hunt, and signals the comeback of Yondu.
