Percy Jackson: The Trollhunter

*I had a hard time looking for a story like this one, so I decided to write one up. Maybe this will encourage others to write stories like this, but even better.*
(Disclaimer: I don't own PJO/HOO or Trollhunters, I'm just borrowing from great minds)

Percy Jackson's life was ordinary at best. He lived with and took care of his hard-working mom, and he went to Arcadia High School with his cousins and his best friend Grover. Other than trying to impress his crush Annabeth, he's got nothing else going for him.

That is until he finds a not-so-ordinary amulet that pulls him into a not-so-ordinary world, and leaves a not-so-ordinary responsibility on his shoulders. Percy's always wished for more excitement in his life, but becoming the first human Trollhunter wasn't what he had in mind.
