X-Men: Age Of Oblivion

Mutantkind stands on the brink of annihilation. Kitty Pryde, leader of the X-Men, stands ready for war. Spider Man, an Avenger, is part of a team of mutant-eradicating meta-humans. But is that all there is? Is anything as it seems. Crappy summary, better story. Kitty PrydeXPeter Parker pairing. First of a very large series.
