These 책 were amazing. The first book was a little light, but the 책 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 더 많이 and 더 많이 important as it goes along, that's something that i like about the 책 alot. They're very mysterious too. There are 4 책 in all, I'd Tell 당신 I 사랑 You, But Then I'd Have To Kill You, 십자가, 크로스 My 심장 And Hope To Spy, Don't Judge A Girl 의해 Her Cover, Only The Good Spy Young. An amazing serious about hilarious, dangerous, mysterious missions. Definetly a great read.
