X-Men Milestones #1

Plot

The biggest and best adventures of Marvel's merry mutants - these are the X-Men Epix! And it doesn't get any more epic than the tale of triumph and tragedy that is the Dark Phoenix Saga! The X-Men have fought many battles, been on galaxy-spanning adventures and defeated enemies of limitless might, but none of it prepared them for the most shocking struggle they would ever face. One of their own, Jean Grey, has gained cosmic power beyond all comprehension - and that power has corrupted her absolutely! Now the X-Men must decide between the life of the friend they cherish...or the possible destruction of the entire universe! This touching tale of ultimate power and the triumph of the human spirit has been a cornerstone of the X-Men mythos for decades. Relive the saga that changed everything!
