50 free The Lost Hero trivia questions with answers — literature quiz, new questions added Oct 2026.
The Lost Hero opens the Heroes of Olympus series with a mystery: a boy named Jason wakes on a bus beside two friends he cannot remember, and within hours all of them are fighting for their lives. Rick Riordan swaps Percy Jackson's familiar voice for a trio of new demigods, each hiding a secret, and sends them across North America on the back of a mechanical dragon. This quiz follows the plot the way a reading check would. It covers who Jason, Piper and Leo really are, the gods who claim them, the monsters and resurrected legends that block their road, the captive they are sent to free and the twist about Jason's past that sets up the rest of the series. A few questions look behind the page at how the book was written and received. It suits readers who have just finished the novel, students revising for a reading quiz and Percy Jackson fans testing their recall. The opening questions are friendly, later ones reach for smaller details, and every answer comes with a short explanation.
