Books Included in This Collection:
I'd Tell You I Love You, But Then I'd Have to Kill You
Welcome to the Gallagher Academy, a school that doubles as a covert training ground for the next generation of spies. In the opening adventure, Cammie Morgan—The Chameleon—juggles exams with covert assignments, and romance with risk. The balance between girlhood mischief and mission-ready grit sets the tone for the series: sharp dialogue, clever disguises, and a fearless heroine who discovers that loyalty and courage often go hand in hand with friendship.

Cross My Heart and Hope to Spy
In this second tale, Cammie faces tougher undercover work that forces her to question loyalty, trust, and the price of keeping secrets. The stakes grow as a mission widens beyond the classroom walls, and readers are treated to brisk action, witty banter, and genuine emotional stakes. Carter refines her spy-world rules while keeping the romance light, ensuring the pages turn quickly and the heart stays engaged.

Don't Judge a Girl by Her Cover
Here, the mission collides with everyday school life as Cammie navigates conspiracies, suspicious allies, and the pressure of living a double life. The pacing remains propulsive, the humor intact, and the stakes rise as danger encroaches from unexpected corners. Readers will relish the clever set-pieces, the female-led ensemble, and the way trust, courage, and discovery weave through every chapter.

Only The Good Spy Young
Dark shadows descend as a dangerous foe presses in, testing Cammie's nerve and her friendships. The plot tightens with daring hijinks, red herrings, and surprising reveals—yet the story never loses its playful energy. Carter keeps the voice bright even when the tension spikes, delivering a high-adrenaline ride that cements the Gallagher Girls' fame as witty, empowering espionage for a young audience.

Out of Sight Out of Time
Memory becomes the mission as Cammie wakes with gaps in her past and a mystery that travels to alpine cliffs and hidden sanctuaries. The narrative leans into atmosphere and suspense, inviting readers to piece together clues while orbiting around questions of identity, family, and trust. A standout entry for building momentum toward the finale, delivering emotional beats and a sense of personal stakes that linger after the last page.

United we Spy
