I would suggest some 'X-Men' for 'X-Mas'!
The entire entire 'Messiah War' storyline between the X-Men and Cable is really fantastic. You can start with right at the beginning with X-Men: Messiah Complex, and then follow the story in Cable: Messiah War and Cable: Waiting For The End of The World, and then of course into the Cable/X-Force Messiah War crossover! That'll get ya through the holidays for sure!
