They've been coming here for thousands of years, using earth as a sanctuary to escape threats from their own kind. Mankind knows them as angels, and one of them left a child upon her death to be raised as a human. Raea is now a high school senior and her life as a human is about to end. The crystal shard she bears is not a pretty pendent, it's a collective of powerful entities who chose her as their keeper, a protector of one of the four shards that powers a machine capable of destroying whole worlds. Those who desire the Starfire's power have sent an agent to find her. Only one person on earth can help her, the last person she never expected.
