All-new X-men Volume 1: Yesterday's X-men - Brian M Bendis

It's a blast from the X-Men's past! Professor X's original five students - Cyclops, Marvel Girl, Iceman, Angel and Beast - are plucked from the past and brought to the present. But what they find - the state of their future selves, and the state of Xavier's dream - is far from the future they dreamed of. How will these young, idealistic heroes react when faced with the crushing knowledge of what their future holds?
