Descendants Rewritten?

Imagine if two unlikely fandoms collided. Now picture if those two fandoms were the Big Four (Elsa, Jack Frost, Hiccup, and Merida) and Percy Jackson. Well, here is a story combining them.
Meet Annie, she is just a regular demigod, or at least she thinks so. Chiron has sent her and a boy named Leo Valdez to Atlanta in search of some demigods. But what happens when Jack Frost, a boy at the high school, starts to fall for Annie?
In this story you will meet characters from Disney, Dream Works,Pixar, and real life people (myself included).
