Probationary Agent

Senior year. Two semesters remain before Raine Campbell and her friends graduate from the School of Necessary Magic. What are the chances of two, nice and quiet semesters?
Chances are pretty slim.
Louper finals are in full swing. Raine's friends are trying to figure out their plans post high school. A teacher is being threatened.
And it wouldn't be a complete semester without Dark Wizards getting involved. Some evil never learns.
Adventure still finds the students. Raine and her friends encounter a witch with a strange necklace in the kemana. When she invites them to a meeting of a secret society, things get interesting - quick.
Can Raine and her friends determine what the society are up to and save their friend before it's too late?
