DO NOT READ (unless you are Danny, Percy or Superdog.) Just don't. Seriously, DON'T. I'm not joking! BE WARNED: if you turn the page, this notebook will EXPLODE! Meet Danny Dingle, aka Experimental Face (ha ha) - super-secret spy and future assistant to the greatest superhero EVER, Metal Face! Danny and Percy know they have to pull out all the stops to beat Danny's arch enemy, Gareth Trumpshaw, who's an evil genius, with an evil genius dad.(They're also big fat cheaters!)Can Dad's special brew of super-fizzy cola save the day? Or will it be down to Superdog to come to the rescue yet again.
