The giant war is over and all Percy and Annabeth wants is to have a normal life or as normal as life can be as a demigod. Annabeth applies for a job at Stark Indestries, Percy decides to apply to be an Avenger to put his skills to good use and be close to Annabeth. (I know that you can't just apply to be an Avenger but this is my story so ya, deal with it)
