A New Family(Percy Jackson/Avenger's)

I've been reading a lot of these lightly, and I've gotten some inspiration. This fic will have some feels. And also spidey is gonna be in it. And let's say Loki turned a new leaf.
Summary:
The Fates are giving Percy a tough life. The War against Gaia is won, but at a cost. The seven except Percy are dead, including Annabeth. And when returning home from camp, he finds his parents dead. Murdered by the being of the pit himself: Tarturus. Percy is sent to live with his long-lost uncle, Tony Stark. How will Percy survive without his friends or his love? Will he accept the family the avengers have made for him?
