Two worlds. One queen determined to rule both. And one teen girl who stands in her way.

Zanzibar MacKenzie knows she's a freak. She has EHS - electrical hypersensitivity - which leaves her trying to live a Stone Age life in the twenty-first century: no internet, no phone, no point really. On her seventeenth birthday she discovers the truth: she can't stand electricity because she's half-fae, and her mixed-blood makes her the only person on Earth able to control the gates that link the fae and human worlds.With the help of Thanriel, an angel charged with keeping the worlds in balance, and Cal, an exiled fae, Zan - the girl who can't flip a light switch - must now learn to control the elemental powers she never knew she had in order to defeat a queen bent on destruction.
