Fledgling by Octavia E. Butler
She woke up alone in a cave. Her body was badly burned and scarred. She couldn’t see. An animal came to her in the cave, she killed it and fed on it, barely remembering after that moment. Time was something that passed unacknowledged. When she was finally able to leave the cave, she found herself wandering aimlessly only to end up at the ruins of homes burned to the ground. And though she felt drawn to the place she didn’t know why. She had no memory of her former self. Then Wright found her, walking in the rain, looking like a 10-year-old child. She fed on him. He would become her first. In time she would discover that she was an Ina, what humans called vampires. But she was the first of her kind with her brown skin and ability to walk in daylight.
