(Not so) Secret Avengers (review)
Anyway I recently picked up a batch of secret Avengers 1-15 for around £1/issue. The premise is that Steve Rogers (no longer Captain America) brings together a group of avengers for secret missions. Key members are Back Widow, Ant Man, Moon Knight, War Machine (blocks the comms channels), Valkyrie , Beast, Prince of Orphans (a new one for me) with guests by Nova (very subtle hero here) and Shang Chi.
Ohh and even though part of the Heroic age these Avengers are not shy about killing.
