Susan Lomond must be defeated. Monroe Poole, teenage evil genius, has suffered her greatest humiliation. Susan Lomond, wretchedly popular football star, surpassed Monroe in their high school's proficiency ranking system, contrary to all laws of reason or rationality. Revenge occupies Monroe's every waking moment, yet she is somehow thwarted at every turn. The explosion detonates too late, the black hole opens up a few feet to the left, the lightning bolt instead strikes the flagpole. The homecoming dance is Monroe's last chance to secure Susan's demise. Will she finally succeed, or will she find that under the light of the disco ball, her obsession has turned from vengeful to something altogether different?
