For 16 years, Daisy has been good. A good daughter, helping out with her autistic younger brother uncomplainingly. A good friend, even when her best friend makes her feel like a third wheel.

But one person won’t let Daisy forget who she used to be: Irish exchange student and brilliant musician Cal.
