The Dragonlady

Rin lived in the wild. All Rin had was her father and Blue, her dragon, and her life was full. She had adopted the dragon, raising it from a hatchling, and he followed her everywhere - until he found a mate, owned by a Lord. Rin was a lowborn, from a different part of the world. Lord Parmer was a highborn, the son of the city Principal.
His life was empty, yet Lord Parmer had anything and everything he wanted, now he owned Rin's dragon too. Dragons mate for life.
Once Parmer discovered who the beautiful owner of the male dragon was, he didn't want to let her go.
Could a lowborn and a highborn find a compromise and be happy?
