The Troll's Apprentice

So the readers know what it's about? Heck, man I don't know what its about. This is my first story, so I'm gonna take me some Scandinavian folklore and go on a meander with it. Pers Josholm, kidnapped at a young age and brought up by a family of trolls, does not have the fine ethics of his fellow species. So when his troll-papa asks for help swindling the people of the valley out of their riches, Pers jumps on without a thought. However, his little decision brings him on a journey of discovery that snowballs and causes him to ask: what is the meaning of being human? Or a troll, for that matter.
