The Rescue of Damndrake. Draghi Chronicles, #2

Can a single dragon free his kind from human servitude?For centuries, humans have ruled while dragons served. The integrated human-dragon society has worked out well. For humans. But Divenire, a disgraced dragon relegated to the Firegard, has yearned to right the imbalance of power. The key is rhenus, the essential metal all dragons need to harden bone and scales. Rumors say the city councils throughout the Territories restrict access to rhenus to keep dragons weak.
When Damndrake, the most powerful dragon in all Terria, emerged from the White Wastes covered in rhenus, Divenire saw a path to a better future. With Damndrake by his side, human leadership could no longer ignore his demands for joint-rule and the equitable distribution of rhenus. He had maneuvered to win her favor, but hadn't planned on falling in love. But others crave Damndrake's rhenus, too, including Divenire's brother, Lucent.
Along with a parade of dragons, a villainous dragon smuggler, and a scheming sorceress from a distant continent, Lucent kidnaps Damndrake and her adopted sister, Blaze. As an albino dragon, Blaze is the fuel the sorceress needs to control dragons. Not knowing who to trust and with his city in peril, Divenire must save them both before Blaze is killed and Damndrake burns them all. The chase is on. If you enjoy stories with heart, and an immersive, epic fantasy soaring with shape-shifting dragons, you'll love The Rescue of Damndrake.
This book continues the events from The Legend of Damndrake, but can be enjoyed as a standalone.
