The Gallagher Academy for Exceptional Young Women is a fairly typical all-girls school - that is, it would be if every school taught advanced martial arts in PE and the latest in chemical warfare in science, and students received extra credit for breaking CIA codes in computer class.

The Gallagher Academy might claim to be a school for geniuses, but it's really a school for spies.

Cammie Morgan is a second-generation Gallagher Girl, and by her sophomore year she's already fluent in 14 languages and capable of killing a man in seven different ways (one of which involves a piece of uncooked spaghetti).

But the one thing the Gallagher Academy hasn't prepared her for is what to do when she falls for a boy who thinks she's an ordinary girl.
