Celest is 6% bird and 2% wolf. When she escapes from the School, she runs into a group of magicians and finds out she is one. But the goddess that choses her is one that eludes everyone and is the complete opposite if herself. Maybe she can help the demigods though. Sorry summary sucks.
As a punishment, Mother Nature takes Jack Frost to Camp Half-Blood to help her run it. Things take a turn for the worst when they found out two foes team up. Now the demigods and the Guardians have to join forces to save the world as they know it. Rating may change.
