Perseus 'Percy' Jackson is a twelve-year-old New Yorker who has dyslexia and ADHD. For reasons unknown, he often finds himself in unique situations that get him kicked out of school. During a school trip to a museum, a bully, Nancy Bobofit, bullies Percy’s friend Grover. At the same time Percy defends his friend, the fountain that they were next to grabs Nancy. However, Nancy believed that she was pushed into the fountain, and lies about the incident to Mrs. Dodds, Percy's pre-algebra teacher. Mrs. Dodds separates Percy from the rest of the class before she transforms into one of the Furies from Greek mythology and attacks him. Mr. Brunner, Percy's Latin teacher, tosses a pen to Percy, and when uncapped, it transforms into a sword. Percy kills Mrs. Dodds, and when he returns to the class, no one seems to remember the pre-algebra teacher. Only Grover seems suspicious when Percy confronts him.
