Irrelevant Number

Farina, Magik, and Luna are three inseparable friends from kindergarten.
Ever since they did everything together, that was until puberty hit them and their parents have to send them to a school. Only not any schools.

The school has a thing to favorite thirteen best students, and each student is a certain number that represents their importance, strength, and power. There are two theories, from lowest to highest, is strongest and best or from highest to the lowest are weak and lucky to have been selected. When it's not. To be between Thirteen is an honor for all because they are all important, powerful and strong in their own way.

Luna is number five and Magik is number eleven. Farina doesn't have a number which makes her irrelevant to all areas. Her classes are plain boring while her friends have fun.

What Farina doesn't know is that her classes aren't anything like normal classes. They are far from boring, especially when she finds a book with a Golden Quiz and decides to give it a go.

What no one expected to happen was for Farina to find the book and take the test. Results are here, and professors don't know what to do.

Farina is an irrelevant number because of her father. He kidnapped her at the age of one and delivered her to the army lab. They did something, and now she is the first person that is 208 while highest, from before was 201.

There is only five of them.
School knows.
Farina is the fifth.
She has a power of chaos and destruction.
That power has to be locked and Farina must choose:

To lock her powers to stay with her friends or to go find her father and show him all that destruction that is coming his way?

Will she chose her friends and all the good she knew or will she become something she promised herself she never will?
