The book talks about how superheroes are treated after a explosion caused by young heros of Tv program to try capture one of the most dangerous villans even for THE AVENGERS . The book tells how the S.H.I.E.L.D agents whant them to reveal their secret identities, as well as they whant them to speak all his powers so that they are stored in the database S.H.I.E.L.D.
 Iron man supports the S.H.I.E.L.D, but Capitain America opposes as the Capitain said from the beginning of the heroes they use a mak to hide his true face, because of that the heros are divided into two '' teams '', those over and those who are against.

In my opinion this is one of the best books I've ever read, containing  well crafted and well told as it develops during the story, making the reades get stuck to it, carring with it the mystery of who will be the winner.
