You remember the war with Gaea right? Leo dies, is brought back to life etcetera, etcetera. What if the war ended with more casualties? What if the fates themselves gave Percy a solo quest? What if it was during World War II? Worry not, this IS a Percy Jackson/Captain America crossover. DISCLAIMER: I DO NOT OWN EITHER...
"Perseus Jackson it is not yet your time. There is still something that you must do. We are sending you back in time..."
Percy has never been on any quests in all of the years that he has been at Camp Half-Blood, so what happens when World War Two breaks out?
