Cousins Dahlia and Sunny Gordon were best friends growing up, bounded by a shared love for making music. When Dahlia's soulful lyrics combined with Sunny's soaring melodies, magic happened, and they promised they would stick together all the way to the top. But a darkness was descending on Sunny, one that would ultimately plunge her into a nightmare of solitude and schizophrenia. After their lives were torn apart, a quarter of a century would pass before the two would meet again.

After long, struggling years, Dahlia's dream of making it in the L.A. music business rests on one song. Desperate for success, Dahlia must find her cousin again in order to secure the rights to the song that promises fame and great fortune.

But Sunny refuses to sign a contract, and Dahlia discovers there are no depths she will not sink in order to get what she wants -- even if it means moving her tragically damaged cousin into her own home. For the first time since she was a girl -- and, perhaps, ever -- she will have to put someone else's needs before her own, and her own life will be unexpectedly transformed in the process.
