In the peaceful kingdom of Astoria, sixteen-year-old Will Fletcher has always lived a quiet life in the remote mountain village of Langdale. But everything changes the night he stumbles upon a strange, glowing stone hidden deep in the forest, a relic pulsing with warmth, as if alive. He has no idea it would lead to an adventure he never imagined. Then, when his village is attacked without warning. Fire and shadow consume everything he's ever known, leaving him with nothing but questions, a hidden past, and the stone that refuses to leave his side. Forced to flee into the unknown, Will soon discovers that the world beyond Langdale is far more dangerous, and magical, than he ever imagined. Ancient forces are stirring. Long-forgotten legends are waking. And at the heart of it all lies the truth about the Riders, the dragons they once soared with...and the boy destined to rise when hope is all but lost. The call has been made. And Will is about to learn that some destinies are written in fire and stone.
