New Avengers, Vol.1 TPB

In the aftermath of Avengers Disassembled come the New Avengers!

With the Avengers disbanded following an attack by one of the teams oldest members, a shadowy villain has taken advantage of their absence to initiate his ominous plans. Employing Electro to disrupt the electrical systems of the maximum-security prison known as Raft, hundreds of super-powered villains are freed to wreak havoc on New Yourk. Without the Avengers to answer the call, a group of heroes must form a makeshift alliance to subdue the rampaging villains and save the city. In the heat of battle, this new team fills the void left by the Avengers demise - the New Avengers.
