Avengers by Jonathan Hickman Omnibus

The Avengers roster expands, a direct response to escalating global threats. Iron Man and Captain America lead this new world order, analyzing the cosmic anomaly known as the White Event. Concurrently, Stark works in secret with the Illuminati, a council of powerful minds, to address a more fundamental crisis: the imminent collapse of reality. This dual mandate forces the team into a war on two fronts. As they mobilize to defend Earth from the alien architects called the Builders, their victory may only clear a path for a greater threat. The arrival of Thanos and his forces turns planetary defense into a desperate holding action.
