Percy Jackson & the Olympians: The Odd One Out

Percy Jackson was painfully aware of how abnormal he was... then he found out the truth of the world, he's a demigod, every mythology exists at once. Oh, and don't forget about crazy guy in a suit with a samurai sword kicks the head off of the minotaur thing chasing him... also he's a reincarnation from a parallel universe and that's the LEAST weird thing about him!
