By day twelve-year-old Alan Cunningham's a normal school boy. But at night his 'gronk' factor kicks in - and suddenly, he's not exactly your average kind of guy. . . . Now that poor Alan's finally got to grips with the fact that he's a Gronk (a nice, friendly werewolf), a group of mad scientists is after him - to them he's just another experiment. Suddenly Alan finds he's got everything to play for in the school's football championships. He thinks it's all over. . . is he right!
