It's a strange world that Orson Scott Card has created. Part religion, part culture, part alien and part technology. Ender may be looking for some healing as he carries the Queen Hive that he nearly killed of the whole species. Novinha may be looking for healing with the guilt of those she love have died.
There are lots of conversations between the many characters in this story. It works. If you are an Ender fan, then this book is a must read. Enter in to a world unlike any you know. Go to a different world were species live a way that only Orson Scott Card could create. Enjoy.
