The Crystal Beat

An action-packed fantasy series for middle grade fans of K-pop and the hottest animated movie of the decade!

For their midyear exam, Hana’s group must achieve flawless kalgunmu (synchronized choreography). A legendary crystal drum promises to “hold the heartbeat of idols past,” but its magic drives them into rivalry instead of rhythm. To pass—and survive—the group must learn that true harmony comes from trust, not shortcuts.
