It's A Secret For a Reason

Gweneviere Callahan is just an average looking girl. But that's as far as her average-ness goes. She is a student at Greystone Institute, home to the best and the brightest students of the entire world. And she is also a spy-in-training.
But her mother doesn't know about what happens at Greystone. And when Mrs. Callahan is taken hostage by a secret organization, Gwen must choose to save her mother and risk destroying the secrets of Greystone, or let her mother die to save Greystone.
