Gallagher Girls: I'd Tell You I Love You, but then I'd Have to Kill You - Ally Carter

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.
