You did not provide any information about the name of the novel. If you can provide more context or information, I will try my best to help you answer your questions.
Elena Greco is one of the main characters. She is a smart and ambitious girl growing up in a working - class neighborhood in Naples. Lila Cerullo is another key character. She is Elena's friend, and she is extremely intelligent and has a strong personality.
Love and its different forms are also a theme. There's the passionate, often tumultuous love between the characters. For example, the love affairs they have which are marked by both great joy and deep pain. And there's also the love within families, which can be both a source of support and a burden.
As far as I know, no. The princess in 'The Neverending Story' is often referred to as Princess Moon Child, and I haven't heard of any new name being given to her.
The significance could vary greatly. It might be a creative concept for a story, perhaps about a character getting a new name and embarking on an unending adventure. It could also be a metaphor for new beginnings that seem to have no end in terms of the possibilities and experiences that follow.
I'm not sure specifically which new name for a princess in 'The Neverending Story'. There are various versions and interpretations, and without more context, it's difficult to give a definite answer.
