From publisher blurb:
This is a new collectible RPG in a Golden Age Superheroes vein: to play, you just need any set of the playbooks, with at least one per player. Each playbook gives you a pre-made character and all the rules needed to play them or to run the game for others.

But how long can she stay one step ahead of those who want the power for themselves?
