When Two Worlds Meet (KOTLC and Percy Jackson crossover)

The war with Gaea is over, and Percy is the last of the seven left. He, along with Nico, Thalia, and Will, were made Gods, but now he doesn't know what to do. His Wise Girl's gone, the rest of the Seven are dead, and his mum and Paul are gone. He's shattered, broken, though he can't let anyone see that. He hardly has anyone left, and the people who are still alive won't be for much longer if he stays around. One day, a group of stranger arrives on his doorstep, and he's taken to a world he apparently 'belongs' in.

Sophie, Fitz, Biana, Linh, Tam, Keefe, Dex, and Marella have been summoned by the Council. Confused as to why they're there, they are told they have a mission. In the Forbidden Cities. They have to bring someone back to the Elven world. That can't be too hard, right?

A/N- Okay. that proves it. I am CRAP, at descriptions. But anyway, please give my story a go. Even if you just read the first chapter, leave a comment, and then never look at it again it'll mean a lot to know you gave it a go. If you have any constructive criticism please give it to me, just don't be mean about my writing please. Also I will NOT tolerate homophobia, transphobia, or racism on my page. Anyway, please try my story, it would mean a lot.

Disclaimer: I am under 20 and a female, so I believe it impossible for me to own these characters. However, I do own the plot.
