PJO Mortals Meet the Demigods With No Mist

DON'T JUDGE A BOOK BY ITS VIEWS. I promise this is a somehow good/bad story. What will happen when the demigods go to hell...jk...they've been there already. But what will happen when they roam around the city just to blend in because of a certain goddess who went on vacation and will never return in a long long time.
