I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
The time-displaced young Jean Grey is held accountable for the actions of the Phoenix Force by the Shi'ar empire. Neither the Guardians of the Galaxy, nor her time-displaced teammates, take kindly to her abduction and trial.
The Guardians come to late to stop the Shi'ar from abducting her, but they do agree to take the X-Men - at least those around - to find Jean.
Add the Starjammers, Scott's father, and a whole bunch of crazy alien hijinks and political maneuvers and you get this graphic novel. Fun, quick, funny, and I really want to continue with the Guardians of the Galaxy series now. And see the movie.
