Synopsis

The first book in the million copy selling Gallagher Girls series set at an elite boarding school for spies. Perfect for fans of XO, Kitty.

A lot of teenage girls feel invisible sometimes. I'm luckier than most because, at my school, that's considered cool.

Gallagher Academy might claim to be a school for geniuses, but it's really a school for spies. Cammie Morgan is fluent in fourteen languages and capable of killing a man in seven different ways (three of which involve a piece of uncooked spaghetti). But she's about to embark on her most dangerous mission yet: falling in love.
