Avengers, Volume 1: World Trust — Geoff Johns

They are Earth's Mightiest Heroes, banded together from across the globe, united in their vow to protect the Earth from those enemies against whom no single super hero can stand alone... and this may be their greatest challenge. The capital cities of every nation on Earth have mysteriously vanished, throwing the planet into anarchy. In this time of extraordinary crisis, the nations of the world turn to the only organization capable of leading them through this time of strife and restoring political, economic and social order; the Avengers. They can defeat any super-villain, but can they govern the entire world?
