Geek Spy

Cassidy Callahan is used to staying in the background, being invisible. She normally keeps to herself, afraid that someone would discover her secret. Bullied and abused, she braves the dangers of everyday life until one day, something strange happens. She receives a letter from a school--- a school for spies, apparently. Disbelieving, she decides to attend Bond's School For Elite Spies to get away from her reality. But soon, her version of reality turns to something entirely different.
She couldn't save herself from her old life, so how will she survive in this life?
