"The world-destroying Phoenix Force is back -- and this time, the Avengers are intent on stopping it. Cyclops and his X-Men have other ideas. To Captain America, the Phoenix threatens doom. To Cyclops, it could mean salvation. Marvel's two greatest leaders wage war, with the Phoenix's chosen host -- Hope Summers -- caught in the middle. As the fate of a girl trained from birth to be a mutant savior hangs in the balance, how far are Captain America and Cyclops willing to go? The answer lies in a battle so big no one world -- no one series -- could contain it!"--Provided by publisher.
