"The Great Abandonment has begun, and now dragons aren’t the only creatures facing extinction in the Fallen Isles. As entire islands rise up from the sea, causing earthquakes, tidal waves, and utter devastation, Mira must use her growing connection with dragons to track a legendary treasure that could stop the destruction—the bones of the first dragon. But finding the treasure means traveling into the land of her greatest enemies. What will it cost Mira to save the dragons, the people she loves, and the only home she’s ever known from total ruin? And what will be left of Mira once the final cataclysm is over?" --Publisher.
