The title kind of explains what the story is about but if you don't know it is PJO/HP crossover. I again feel as if since the story was originally first POV it doesn't flow and was also once again based off of a story on fanfiction.net called Secrets and Surprises (which has been discontinued (I believe)). 

Should I...Rewrite Hogwarts School of Wizards and Demigods?

Yes
or
No

If Yes

Should I...Keep the story up but rewrite it completely in a new book?
or
Should I...Take down the story and rewrite it?

If No

How should I continue with the story?
