Cliche and Facepalm Worthy PJO Fanfictions

Hi! So, just what the title says, really. Remember, this is JUST MY OPINIONS and it may contradict what A LOT of people think, but other parts might be better. If you don't like one thing that I say, PLEASE don't stop reading just because of it.
Disclaimer: a lot of Rick Riordan's characters (duh) and if I say something similar to what someone else did, I'm sorry and I probably wasn't trying to copy them.
Thanks and please read!
