New Order
Inferno was in full swing, the Avengers are gone, and the heroes are literary picking up heroes along the way. It may seem like a bunch of story lines bunched into one, but it works together well. This story happens before Captain America issue 350 and after Thor issue 400 (clever the way Marvel had all three come up the same month). The team battles the Nanny, an egg shaped villain out to capture mutant children (no, seriously) and then fights to stop Inferno.
Not a bad tale, but you might need a dozen books from the X-Men books and spin-offs to fully understand it.
The only problem I have with this book was being that I'm a fan of the Fantastic Four, it was great seeing Reed and Sue in action, but come on, no new costumes. Maybe if the would of stayed a little longer.
The book also includes a listing of the Avengers and a retelling of issue 1, vol 1.
