These 图书 were amazing. The first book was a little light, but the 图书 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 更多 and 更多 important as it goes along, that's something that i like about the 图书 alot. They're very mysterious too. There are 4 图书 in all, I'd Tell 你 I 爱情 You, But Then I'd Have To Kill You, 交叉, 十字架 My 心 And Hope To Spy, Don't Judge A Girl 由 Her Cover, Only The Good Spy Young. An amazing serious about hilarious, dangerous, mysterious missions. Definetly a great read.
