About This Book
The heavy thud of dinosaur footsteps shakes the ground beneath Carthus as he races through the hidden kingdom where these mighty creatures roam free. The sharp scent of earth and ancient scales fills the air, and the roar of a distant T-Rex echoes like a challenge. Carthus, a determined orphan with a big dream, must team up with unlikely friends to ride, fly, and joust—because their future depends on more than just winning.

He dreams of becoming a dinosaur rider but faces challenges both from his social status and hostile schoolmasters.
