The Lightning Thief by Rick Riordan

Percy Jackson is a below-average student on a routine school field trip when his teacher suddenly morphs into a harpy and attacks him. Percy’s mom whisks him off to Camp Half Blood, a refuge for demigods of Olympus’ deities, with little explanation. There, he learns his father is Poseidon, God of the Sea, and Percy finds himself in the middle of simmering tensions between the gods. To prevent an all-out heavenly war and save his mom, Percy and his two new friends embark on a dangerous quest across the country. The first in Riordan’s best-selling and beloved series is nonstop action with Greek mythology woven into a modern tapestry as Percy and his friends battle mythological monsters, solve ancient riddles, and appease gods who’ve never stopped meddling with humanity, all while navigating their way through middle America. The Lightning Thief is an epic story of a boy’s perilous quest as he discovers his greater purpose and learns the power of friendship.
