Xander Stone is your average twelve-year-old boy. And, like any average twelve-year-old boy, he didn't believe in unicorns. No way. No how. NOT A CHANCE. Then one day - BLECH! - one puked on him. Yes, PUKED on him! Filthy, sticky-icky, rainbow-coloured puke. If seeing is believing, Xander got beliefed all over his favourite trainers. UNICORNS WERE REAL! Not the beautiful, brightly coloured, tra-la-la-ing ones in fairy tales. But stinky, zombie, rainbow-puking ones. At that moment, Xander Stone vowed to protect them and their disgusting secret at all costs - oh, and to keep his trainers squeaky clean.
