The Boy and his Cat

Kat Hughes was the perfect S.H.I.E.L.D agent, working closely with the avengers, newly promoted, and feeling absolutely great with her life.
Until she stumbled upon a little boy and his cat in an alleyway.
A boy called Percy Jackson, the boy who would change her life forever.
Her new colleagues, the Avengers, are trilled with her discovery, and together with the super team she learns to raise a hyperactive Percy.
How does Loki fit in to this? And will her boss, Nick Fury, approve of her new son?
