The Olympians (Heroes of Olympus AU)

Piper, Jason, Thalia, Reyna, Annabeth, Percy, Leo, Frank, Hazel, Nico, and Will are a group of 20 year olds. They created an organization called 'The Olympians' where they plot against The Titans, who are a group of criminals aspiring to take over the country. No one of importance believes The Olympians about The Titans. The Olympians have to work by themselves to save the country from the power-hungry, blood-thirsty Titans.
