Uncanny X-Men #500 - #505

Uncanny X-Men #500 - #505 - Sentinels? What? And Magneto? And is that the Master Mold? What the hell is going on in San Francisco now that the Uncanny X-Men have relocated there? They've got a new Headquarters and a new status quo as the gauntlet is thrown for a new era of mutantkind. It's all here in the double-sized anniversary issue that sets up the plotlines that will be developed over the next year in Uncanny.
