Mrs. Smith’s Spy School for Girls is a three-book middle-grade series by Beth McMullen, published between 2017 and 2019. The series follows Abigail Hunter, a twelve-year-old whose mother drops her off at an exclusive boarding school and vanishes. Abby soon learns that the Smith School is not what it appears to be, and that the students are being trained for something far more exciting than algebra.
The trilogy blends school story conventions with spy adventure, as Abby navigates friendships, rivalries, and genuine danger. Power Play and Double Cross raise the stakes as Abby becomes more skilled and more deeply involved in the school’s secret operations. McMullen keeps the tone fun and exciting while giving Abby room to grow as a character.
