Percy Jackson The Betrayed Hero

This is probably going to end up being a Pertemis pairing. However, it will for sure NOT be a percyXmulti story, I personally don't like reading or writing those, sorry not sorry. This will start off as a story where Percy was able to reach his trusty sword Riptide and cut the silk string that was pulling Annabeth down into Tartarus, but instead he falls down into the pit by alone.
