Cassandra Jackson: The Lightning Thief

Cassandra Chase is a half-blood that has been going to Camp-Half-Blood since she was 4. When she goes under cover with Chiron and Grover at Yancy academy, and meets Percy Jackson, and her life flips upside down. What will happen? (Please don't judge on description. It kinda sucks) FYI I DO NOT OWN PERCY JACKSON OR ANY OF THE CHARACTERS OR PLOT. EXCEPT FOR CASSANDRA. I ALSO DO NOT OWN THE COVER! IT BELONGS TO THE ARTIST. WHICH IS NOT ME!
