Wings of flame: revenge of the fire

Emma was framed. Hurt. She went insane. She is killing for revenge and will spill anyone's blood to do so. She is a broken and bloodthirsty girl who came to protect, but couldn't handle the grip of her new world. Emma was flying with her head in the clouds protecting her friends until someone cut off her wings and put her in prison. Once she finds this man, she will show no mercy as she burns him with her own rage. If, her powers can resist the pulls of earth. And her.

(The characters I use in this book like 'Chara and 'Asriel' don't belong to me. They belong to Toby Fox, the creator of undertale.)
