Avengers / Hickman, Jonathan

"And there came a day, a day unlike any other, when Earth's Mightiest Heroes found themselves united against a common threat! And on that day the Avengers were born, to fight the foes no single super hero could withstand! But what happened the next day? You only think you know the story! A hidden foe manipulates the fledgling Avengers from the shadows, meticulously sowing the seeds of discord and mistrust--and causing the new teammates to question the very ties that bind them together as they hunt for the fugitive Hulk"--Back cover.

When Captain America extends the roster of the Avengers to the interplanetary level, some surprising people answer the call. Their first mission takes them first to Mars then back to Earth's Savage Land. And, when the Shi'ar Imperial Guard fall on a dead moon, the Avengers cross the galaxy to battle invaders who want to remake Earth.
