Earth's Mightiest Heroes and the Children of the Atom assemble again! Innocent people and world leaders are dead after simultaneous attacks on the U.S. and Krakoan governments. False-flag attacks meant to whip up anti-mutant hysteria are unfolding and, hey, some of Steve Rogers' best friends are mutants. So Captain America enlists Rogue, Deadpool, Quicksilver, Psylocke and Monet to solve the mystery of who the new, murderous Captain Krakoa is - and stop his team of killers from igniting the fires of a new world war! As the Uncanny Avengers run smack into a new Mutant Liberation Front, blood is spilled, romantic sparks fly - and Captain Krakoa is unmasked!
