More correctly:
Percy Jackson & the Olympians.
This is the story of young Perseus Jackson. A young boy who discovers he is a demigod, half-god and half-human, and is sent to Camp Halfblood after a vicious attack from the Minotaur. Discovering the true identity of himself and his biological father, a Greek god of Olympus, Percy Jackson and his new friends of Camp Halfblood unite to fight against mythological creatures to prevent a mysterious evil from causing a war between the Greek gods. Written by Rick Riordan, the story is a series made up of five books:
1. The Lightning Thief
2. Sea of Monsters
3. Titan's Curse
4. Battle of the Labyrinth
5. The Last Olympian
Upon first reading them, I am absolutely addicted to these books. I'm currently reading the second one!
