Graphic Novel Reading Group discussion

I've always liked the X-Men (being a fan of the movies and such), and I was wondering which series and authors of X-Men comics I should read? I currently have Days of Future Past and I was thinking of getting the Dark Phoenix Saga.
I'm open to any suggestions!

Thanks so much!

If you want to try the classics I recommend God Loves, Man Kills and Days of Future Past.

Thanks guys! I'll be sure to pick up all the classics soon!
