Uncanny Avengers Issue # 17

A letter in the future. To a daughter left behind by a parent on a quest. A parent who was there the day when the courage of Earth proved insufficient...

New York. Under a preternatural red sky, the world watches Exitar, Executioner for the Celestials, descend. In the streets, heroes combine their efforts to keep calm while geniuses try to build a stopgap. Hulk will hold Doctor Doom's force-field generator in place as it protects the world. In low Earth orbit, a coalition of super-humans will delay the cosmic god, and everyone hopes the Avengers Unity Squad, who are outside the force-field, can find a way to save the world.
