Freaks : a novel
(Book)

"Four high-school friends suffer daily humiliation at the hands of three bullies. When the friends accidentally open a portal to another dimension, they unintentionally allow terrifying, other-worldly creatures to invade their small Arkansas town. Discovering that they are now endowed with strange superpowers, the four teens dub themselves 'Freaks,' the very name their tormentors used to ridicule them. The Freaks must fight to save the lives of family and friends now in mortal peril and thwart a secret government task force that appears to be hunting them." --book jacket
