Three demigods. One impossible prophecy. Zero time to waste.

The Lost Hero kicks off a brand-new adventure in the world of Greek mythology—but with a twist only Rick Riordan can deliver. If you're into epic quests, flawed heroes, talking dragons, and monsters that don't stay dead, you're exactly where you need to be.

Here’s the punch: Over 30 million readers have devoured Riordan’s mythological worlds. Why? Because he makes ancient gods feel like high schoolers with attitude—and his characters are as messy, lovable, and real as your group chat. This isn’t just a story. It’s a full-blown universe you’re about to dive into.

Jason wakes up on a school bus with no memory. Piper has a secret that could break her. Leo hides pain behind humor and mechanical genius. Together, they’ve got to survive a training camp for demigods, a cross-country monster hunt, and a prophecy that could destroy the world. Casual, right?
