I Raised Him. He Let Me Drown.

After ten years of devotion, Evelyn is betrayed by Lucian, the holy white dragon she saved and raised, when he rescues her charming sister Vivian from a deadly flood and leaves Evelyn to die. Reborn on the day she first found two dragon hatchlings, Evelyn refuses to be anyone’s sacrifice again. But Lucian remembers the past too, and Vivian is determined to steal every blessing meant for her sister. As academy dreams, stolen grace, and ancient dragon secrets collide, Evelyn discovers the truth of her bloodline: she is not a powerless human girl, but the Abyss Dragon Queen.
