My girlfriend read a book during her childtime and only remembers one name "nuvilas" (although I'm not sure if this is the correct spelling because I've already searched everywhere on the internet). I think it's a children's book.
I've been looking like crazy for this book because I wanted to present it to her for christmas, can somebody help me ...

thx in advance

Any idea what the book was about?

Any chance there were names or words in Spanish in it?
