Fifteen-year-old Jim Lake is just an ordinary teenager. That is, of course, until he is chosen to be the first human protector of a secret world of Trolls living below his peaceful hometown of Arcadia. If Jim fails at his mission, humankind will cease to exist. The fate of the world rests on his shoulders. Can Jim be the Trollhunter and stay a normal kid at the same time? Probably not. But being normal was never really any fun anyway.
