The Avengers and the unexpected meeting (An Avengers and Percy Jackson fanfic)

Percy's biggest fear has come true, he has lost almost everything he loves. His mother is dead, his step-father is in such a state of shock he can't talk, Annabeth cheated on him the day of his mothers funeral (Sorry fellow Percabeths) and the whole camp thinks he tried to kill Frank. What happens when the broken demigod meets the Avengers and they do a sing-a-long?
