I love the premise--a spy school for girls. The main character is the headmistress's daughter, Cameron, whose father died under classified circumstances. The main takeaway for Cammie the fall semester of her sophomore year, when she meets a boy from the town, is that spying is hard, but being a girl is harder. 

Cammie and her friends are overly starry eyed and heteronormative, and Cam's best friend, who is Black is referred to as exotic looking, so, it's not a perfect novel or anything, but it's fun enough.
