Avengers: Endless Wartime — Warren Ellis

An abomination, long thought buried, has resurfaced in a war-torn land. But now it wears an American flag. Faced with another nightmare reborn, Captain America will not stand for yet more death at the hands of a ghost from his past. Haunted by his greatest shame, Thor must renew the hunt for a familiar beast. At their side, an assemblage of allies united to end the threats no one of them could face alone. They are soldiers. Warriors. Comrades-in-arms. Mighty heroes led by a living legend, stronger together than apart. They are the Avengers.
