Synopsis

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

Most people believe me when I lie. But the boy in front of me was a trained operative.

At Gallagher Academy, Cammie Morgan has been fake kidnapped once, almost actually kidnapped twice, and targeted by one criminal organisation and two very cute boys. But when she discovers one of her most-trusted allies is a rogue double-agent, Cammie faces her most terrifying mission as she questions her trust in her classmates, her teachers, and even her own heart.
