We Are The Song by Catherine Bakewell

Twelve-year-old Elissa has been raised in seclusion as a devotee of the Mother Goddess. She is a special child, a blessed child, a child who can sing miracles into being. Her voice can heal wounds, halt landslides, cure hunger—and even end wars.

But there are those who would use her gift for darker things. And when Elissa finds herself the farthest from home she’s ever been—along with her vain and jealous music tutor, Lucio—she will have to develop the judgment to decide who wants to use her song to heal… and who wants to use her song to hurt.
