Gifted

Kara was an ordinary girl until one day when she got bitten by a spider. But not just any spider... A RADIOACTIVE one. Suddenly, she finds that she can turn invisible, electrocute people, and jump both high and far. She hears out about Charles Xavier's School For Gifted Kids through Anathema Devichi, a friend of hers who lives there. It's chock full of other minors with gifts and powers. Like Dale, who can fly and throw you anywhere in the multiverse. Or Luke, who is telepathic and can read your mind, tell what you're gonna do next and talk to you wordlessly. Join these four and many more in a tale of suspense, surprise, shock, and adventure around the world to defeat the dreaded Aphis species and get to their classes on time.

I got the idea for this in a dream, that's how things are a little bit messed up and how it's a mix of two or more movies. Also, please be warned that I write very long books, so there may only be two or three chapters, but they're really long.
