Halsey is a sixteen-year-old mechanic with a secret: she's A werewolf. The very last one of existences. When trouble brews in her small town, she is determined to keep a low profile without giving into the beast that urges to break through the surface-but when the Prince of Alstar, Arthur tumbles litterally into her life, she forgets all about the dangers of falling in love with a human. After all, humans killed her parents.
