Secret Avengers by Rick Remender

Rick Remender’s 2012–2013 Secret Avengers run at Marvel packs a high-octane espionage-and-superhero saga into just three issues, with art duties split between Arthur Adams and Matteo Scalera. The series follows a covert team of Avengers—including Black Widow, Captain Britain, Clint Barton, Eric O’Grady, and Flash Thompson—as they tackle black-ops missions that push their loyalties and skills to the limit. It’s a tight, intense burst of Cold War–style intrigue and cosmic-level stakes, showcasing Remender’s knack for character-driven action in a short, punchy arc.
