Cross My Heart and Hope to Spy (Gallagher Girls, #2)
Cammie Morgan is back, and it's clear that her life hasn't calmed down since the events of I'd Tell You I Love You, But Then I'd Have to Kill You. At first, giddy anticipation is in the air. Gallagher Academy, Cammie's elite spy school, is hosting a visit from a covert training center for boys. Soon after the boys' arrival, though, everything goes dangerously awry when a series of security breaches are discovered at the academy. Worse yet, teenage agent-in-training Cammie is being blamed for the penetration. With the school's top-secret status at risk, the Gallagher Girls have to work quickly to save their beloved school.
