Rhyme has a secret. Something magical happens every time she plays her violin. But until she meets Cath, the newest student in her school, she thought the secret was hers to bear alone. Cath is a beautiful and talented boy she can't help but fall in love with. Can she trust him with her secret?

Cath's flighty parents decide it's time for him to face the real world. When he meets the equally talented Rhyme in band class, his self-confidence is shaken, and his life is turned upside down. Questions play like a concerto on repeat through his mind. Who is she? Where did she come from? Why is she so different from everyone else? Outcast, bullied, and determined, Cath will stop at nothing to find the answers, even if it means tearing her apart.

Growing up is hard. Growing up fairy is even harder.
