In her fourth adventure, teenage spy-in-training Cammie is still being pursued by the mysterious Circle of Cavan. Now she's also forced to consider that her favorite teacher, another new teacher, and her crush might all be out to get her. In this suspenseful spy adventure, the line between good and evil blurs as Cammie and her friends try to discover the truth.

Gr 6-10 Cameron Morgan's junior year at an elite spy school is off to an inauspicious start. She's lured away from her friends, held hostage by a former teacher-turned-rogue, and given the cryptic message: "follow the pigeons." Cammie knows the Circle (evil terrorist operatives so secret many doubt their existence) is still after her. Gallagher Academy is now on a ridiculously high security alert and everyone, including teachers and friends, is suspect. Questions abound. Who can Cammie trust? Why does the Circle want her? And can she possibly have a relationship with super-cute double-agent Zach? Reading the first three books in the series is helpful but not necessary. There's enough background information to bring readers up to speed on Cammie's world and past adventures. Humorous, fast-paced fun. Kelly Roth, Bartow County Public Library, Cartersville, GA
