How to save: The boy with the sea green eyes

Hello Readers,
This is the first book I what I am calling the 'How to Save series' some themes may be upsetting or triggering, I will try to add all warnings but I may miss some. This first book will be a Percy Jackson and the Avengers crossover!

After losing his friends, family and the love of his life Percy just wants a break. He just wants to be able to curl up in a ball and cry until he can't cry anymore and then cry some more. But no. The fates hate him. He is sent to live with his only living family member in some high security building in the middle of nowhere. This uncle of his (on the mortal side of course) who is apparently a millionaire and likes to dress in a metal suit and parade around with his cosplaying friends 'saving' the world. Yup. The fates hated him.
