Hurt ( new moon )

Edward left her. She loved him. He broke her heart. She turned into a monster.
Bella is now known as the most feared vampire in the world. She lives in Voltera with the Volturi. She hates Edward. All because Edward left her while she was pregnant with his child.
Edward didn't know what he was doing. He thought he was keeping her safe. He didn't know she turned into a vampire nor that she had a child.
What happens when the Cullens show up in Voltera and find Bella still alive. But she is a hot bitch?
