50 free The Lightning Thief trivia questions with answers — literature quiz, new questions added Oct 2026.
The Lightning Thief is where it all starts for Percy Jackson. A twelve-year-old who keeps getting kicked out of schools learns that the Greek gods are real, that monsters are hunting him, and that someone has stolen the most powerful weapon on Olympus. Rick Riordan's 2005 novel turned old myths into a cross-country road trip, and it has been a classroom and book-club favorite ever since. This quiz follows the book from its first chapter to its last. Early questions cover Percy's life before camp and his arrival at Camp Half-Blood; later ones track the quest west, the journey into the Underworld and the twist ending. A few look at how the novel was written and adapted for the screen. It is written for readers who have just finished the book, students preparing for a class quiz on chapters 1 to 22, and longtime fans who want to see how much of the first adventure they still remember. Every answer comes with a short explanation.
