Percy Jackson can't seem to focus on his schoolwork or control his temper. And lately, being at school is only getting worse -- Percy could have sworn his pre-algebra teacher turned into a monster and tried to kill him. When Percy's mom finds out, she knows it's time that he knew the truth about where he came from, and that he go to the one place he'll be safe. She sends Percy to Camp Half-Blood, a summer camp for demigods, where he learns that the father he never knew is Poseidon, God of the Sea. Soon, a mystery unfolds and Percy sets out on a quest across the United States to reach the gates of the Underworld (located in Hollywood) and prevent a catastrophic war between the gods. Full of Greek mythology humor.
Book 1 of the Percy Jackson and the Olympians series.
