Friday the thirteenth was totally normal. By ‘normal’, I mean that my good-for-nothing brother was absolutely not turned into a zebra while I was being suffocated by a million frogs. There were no levitation pills, time-freezing guns or robot octopuses, and I certainly didn’t turn my classmate into a human tornado that destroyed most of the town. That would be preposterous.

No, it was just another ‘normal’ day with my best friend Nate – who just happens to be a genius.
