She commissioned my sister, Mary Myfanwy, to write and perform a song to accompany the promotional video clip.
Mary wrote a soulful song that shared the same title as the book.
This can now be heard on Youtube. As her brother I'm very proud of little sis! She has a deep, rich voice that is surprising for her age (18) and slight build. Hopefully she'll release a few more songs on Youtube in the near future :)
