Fantastic Four and The Avengers (Book 1)

Its been 2 years since the Silver Surfer, and it has all been good since, well except an alien invasion in New York. The Fantastic Four still see eachother, but there is almost no crimefighting anymore. But what happens when various villians team up to try to take over the world, including Loki, someone who calls himself the Exterminator, and someone who calls himself the Detroyer. Will the Four have to call in back up? What will happen when the Avengers and the Four combine? Total chaos, craziness, and arguments happen, but hopefully it will all turn out for the best.
