Percy Jackson is a 12 year old boy. He has ADHD and dyslexia. He has been thrown out of many schools. On a trip with his mother, he meets his friend Grover, a satyr (half-goat, half-human). Grover tells Percy's mother that Percy must go to a camp. When they drive towards the camp, a Minotaur (monster) attacks them and grabs Percy's mother. She dissolves into gold sparkles of light, but Grover and Percy escape.
