I really liked the strong voice of the main character in this book. Before reading it I did not know this myth so I don't have any opinions on changes made or expansions on the original ideas. One of the things I loved about this book is the thread of love for her sister that runs through the entire narrative, it's not often that you see intense sibling devotion in stories and I'm always delighted by it. I also enjoyed the way the gods were portrayed here, it's different than many authors have done it but beautiful imo.
