Riptide (Avengers/Percy Jackson Crossover)

Percy-hero of olympus, defeater of oh-to-many monsters, son of poseidon, and...five year old? After a curse from Kronos, Percy, Annabeth, Nico, and Thalia are stuck as children. Lost and grieving, they need to find a way to survive in the un-child-friendly world.

Right after stopping the Chitauri attack (before anything else) the avengers are taking a break. When Fury starts bugging them to train children to eventually save the world in their place, they start to look for possible recruits.

What will happen when they meet? Will Annabeth and Percy be able to keep their secret? What will happen if S.H.I.E.L.D. finds out about them?

Set after most of the HOO series, doesn't follow books exactly.
Set after the FIRST Avengers movie, but none of the others.
