Ever since scrappy commoner Sebastian Smith and noble Lady Agathea Flamma were paired as Dragon Riders, their bond has defied expectations. But as dark forces stir in the south, threatening the Middle Kingdom, that bond faces its greatest challenge yet.

Seb uncovers a chilling truth: Lord Vincent has returned, bent on releasing the ancient evil known as the Darkening-a force capable of wiping out the entire realm. To stop him, Seb, Thea, and their shared dragon, Kalax, must embark on a perilous quest to find the legendary Dragon Stones before their power falls into the wrong hands.

But the journey isn't just about defeating old enemies. To stand a chance, Thea must conquer her own inner demons, and Seb will have to become the leader his kingdom desperately needs... before the Darkening engulfs them all.

Step into the Torvald Dragon Rider Universe-an interconnected saga told across six legendary dragon trilogies, eighteen books in all. Each trilogy can be read on its own, or experienced together as part of the epic saga of fire, flight, and destiny.
