X-Men: FF
Collecting X-MEN (2010) #15.1 and #16-19.
The X-Men and the FF team up when strange happenings in the Bermuda Triangle threaten the Marvel Universe. Yes, you've seen the X-Men and the FF interact before, but never with Magneto and Dr. Doom on the side of the angels. Don't miss this landmark team-up with an adventure you have to see to believe. Plus: When a medicine woman is at death's door, the demons she's been containing for decades are looking forward to their freedom. Good news: The X-Men are on the scene. Bad news: These demons are out of our mutant super heroes' league. It would be nice to have help from Ghost Rider, but is the new Spirit of Vengeance friend or foe?
