I'd Tell You I Love You, But Then I'd Have to Kill You

by Carter, Ally

Cammie Morgan attends the Gallagher Academy for Exceptional Young Women, which is a polite way of saying she is training to be a world-class spy. While she can disable an opponent in seconds and speak fourteen languages, she is completely baffled by the most dangerous mission of all: dating a normal boy. This book is a breezy, high-energy take on the boarding school genre that prioritizes sharp banter and genuine friendship over dark grit. The pacing is snappy, making it feel like a secret mission you are reading under the covers with a flashlight. It is the perfect pick for anyone who wants a story that balances high-stakes espionage with the awkward, relatable reality of being a teenager. If you enjoy clever heroines and stories where the social hierarchy is just as complicated as the tactical training, you will have a blast here.
