The Demi-Goddess Seraphina

I wanted to try to make an original story for once instead of fan-fiction as that is what I usually do.
This is the story of Seraphina she is a Demi-Goddess which in her world means a Goddess-in-Training. She is one of the few magical creatures chosen to be a Goddess-in-Training it is a rare thing to be chosen and something that shouldn't be taken lightly. She will have to find out what she will become the goddess of and what her powers will be. Along the way there will be problems that she has to either solve or be sent back to her crazy harpy siblings.
