I'm looking for this book, I can't remember the title. it's about a gin who loses her powers and has to rely on someone to keep her alive
I would suggest the series Children of the Lamp, it is a series of fantasty for senior children as well as adolescents and adults written by the British author P.B. Kerr. It tells the story of twins John and Philippa, as they discover how to act in the world of djinn. (genies). The story has a variety of themes, family, adventure, and loyalty being a few.
