These livres were amazing. The first book was a little light, but the livres get way better. Ally Carter is a genius for being able to produce such amazing books. The girls in the book are so strong, brave, and independant. The boys in the book get plus and plus important as it goes along, that's something that i like about the livres alot. They're very mysterious too. There are 4 livres in all, I'd Tell toi I l’amour You, But Then I'd Have To Kill You, traverser, croix My cœur, coeur And Hope To Spy, Don't Judge A Girl par Her Cover, Only The Good Spy Young. An amazing serious about hilarious, dangerous, mysterious missions. Definetly a great read.
