Avengers: No Surrender #[nn]

This hardcover collects the complete 'No Surrender' storyline from Marvel's Avengers titles, a weekly 16-part saga that ran through Avengers #675-690 in early 2018. The story brings together multiple Avengers rosters—including the main team, the Unity Squad, and the U.S.Avengers—to face the cosmic threat of the Challenger, a being who pits Earth's heroes against a mysterious enemy known as the Grandmaster. Written by Mark Waid, Al Ewing, and Jim Zub with art by a rotating team of illustrators, this event is notable for its real-time weekly release format and its role in setting up the subsequent 'No Road Home' arc.
