Starfire Angels

Raea's life as a human is about to end and a new life will begin. The crystal shard she bears is not a pretty pendant; it's part of the heart of a machine capable of destroying whole worlds. Those who desire the power have sent an agent to find her, but she's too busy evading a nosy reporter, dating a hot new foreign student, and learning what she really is. Only one person on Earth can help her, but he's not from Earth.
