I read this story a while back and I decided to read it again but I don't remember the title and I can't find it anywhere.

It might be a Percy Jackson crossover. Bella is daughter of Artemis and when she turns 18 she becomes the Goddess of the Moon. Before her 18th birthday she moves to Forks to live with her father, Charlie, and meets the Cullens. Two demi-goddess friends came with her. One of them was a daughter Hades.

I believe that it had around 19 chapters when I last read it.

If anyone knows what happened to this story then please let me know.
