What's the name of a greek children's book about a dryad who wants to be human and so goes to Delphi for a way?

I read this Greek children's book years ago and am looking for it for my niece. The dryad in the story is anxious to become human and so she goes looking for a way to do so and in the process is told by the Oracle at Delphi that she has to die first.





Does anyone know the name or the author so I can look for it?
