New X-Men: Imperial and New Worlds (Grant Morrison)

These X-Men volumes were interesting - a vastly more complicated look at the X-Men than I've had before, what with aliens and heaps of characters I'd never heard of. I think for that reason I found these slower to get into than I have other series, but I enjoyed them enough to persevere. I can follow the stories, even if I'm a little confused half the time.
