It is a series about three girls from different backgrounds: they are the daughters of the Big Three. Also, they are the granddaughters of Tartarus, Uranus, and Pontus. Even though they have a terrible past, the girls have other things to worry about, along with their mortal lives at school. A new danger is approaching. It would take the three of them to stop it before it's too late. The Fate of Olympus is in their hands. Will the girls succeed or fail in their killer quest?P.S. Three books are going to be in this main series. This is a fanfiction for the Percy Jackson Universe. I have a few OC characters. Camp Half Blood and all PJO characters belong to Rick Riordan.
