Good story pls read

After the defeat against Gaea Percy Jackson reached his limit. The seven, Nico, Thalia, and others died so he decided that he was going to go back to his mom and Paul's house/apartment, when he got there...he found them dead, so he ran, and then he fell... Into the one and only Hell Pit Tartarus. He's been down there for years getting tortured, what happens when a bright light appears, and an unknown force brings him do a different dimension?! (I own everything (besides the characters) unless I say so) it gets better around chapter 15 or 20 I DO NOT OWN PJO OR BNHA I ONLY OWN THE PLOT (characters might be a little (very)OOC)
