Saving the world isn't easy. It's even harder when you're only nine.
Kelly Donovan used to be a nobody. Well, a smart nobody. Skipping ahead a year in school made her the smallest kid in fifth grade and a target for bullies in search of an easy mark. She tried to follow her father's advice and ignore them, but it didn't do any good. Escaping into her favorite comic books at least helped her through the day. Who needs friends anyway?

Sometimes, dreams find a way to come true, even if nobody asked them to.

Aliens bombard the Earth with gigantic glowing red crystals to restore its failing magnetic field. Soon after the seemingly benevolent invasion, Kelly discovers her wildest, happiest fantasy come to life: she has superpowers, along with roughly two percent of the population. Her strong good nature leads her to adopt the heroic persona of bergirl. However, she has one major problem...

Her dad's turning into a mad scientist.

It's difficult to be a hero, especially when your father's a bad guy.
