There's no such thing as superheroes? Is there?
Sienna Miller knows about superheroes. They are a thing you read about in comic books or watch movies about. Fun, but the occasional unpowered costumed vigilante aside no one actually believes in them. What Sienna doesn’t know is that all that is about to change and she and her best friend Wendy are going to be at the heart of it.
After a meteor explodes above her home town of Castleham a strange magenta mist engulfs the town. Sienna and her friends are caught in the chaos and as they try to escape she finds herself possessed of strange powers.
As the town recovers from the disaster it becomes apparent that she’s not the only one and someone is hunting down and killing the affected. Sienna just wants to lay low and figure out what’s happened to her but Wendy has other ideas. The hunters have some way of locating their targets, so Sienna has to fight back and while Wendy has no obvious superpowers she does have a way to help.
