Mortals Meet Demigods/ One shots

Ok, so at first, I was just gonna do mortals meet, but, I changed it to mortals meet and one shots because I was running out of ideas. So, if you want to read one shots, go later into the book. BTW, FIRST BOOK, DON'T JUDGE.
DISCLAIMER: I don't own any of the Heroes of Olympus characters. Rick Riordan does. And art credits not to me; found it online:)
