“I know in the spy movies it always looks really cool when the operative goes from a maid's uniform to a slinky, sexy, ballgown in the amount of time it takes an elevator to climb three floors. Well, I don't know how it is for TV spies, but I can tell you that even with Velcro, the art of the quick change is one that must take a lot of practice (not to mention better lighting than one is likely to find in a tunnel that was once part of the underground railroad).”

“I suppose a lot of teenage girls feel invisible sometimes, like they just disappear. Well, that's me—Cammie the Chameleon. But I'm luckier than most because, at my school, that's considered cool. I go to a school for spies.”

“And as every spy knows, common enemies are how allies always begin.”

“I wanted to pull away, remind him that I was a big girl, a highly trained operative, a spy - that I'd been training for this mission my entire life, and I wasn't going to be left on the sidelines. But in the dim space with Zach pressed tightly against me, only one thought came to mind. I kissed him - longer and deeper than I ever had before. The school was not watching us this time. There was nothing playful in the tone. We were just two people kissing as if for the first time, as if it might be the last. And then I broke away. "So," I asked, as if I got kissed like that all the time (which, believe me, I don't), "where is it you're taking me again?" "The tombs.”

“You know,' I whispered, 'some girls might think it's creepy having a boy watch them sleep.'He smirked and pointed to himself. 'Spy.''Oh.' I nodded. 'Right. So you're a trained Peeping Tom.''Product of the best peeping academies in the country.''Well, now I feel much better.''You should.”

“Despite having known him for almost a year, there were a lot of things I still didn't know about Zachary Goode. Like how soap and shampoo could smell so much better on him than anyone else. Like where he went when he wasn't mysteriously showing up at random (and frequently dangerous) points in my life. And, most of all, I didn't know how, when he mentioned the jacket, he made me think about the sweet, romantic part of the night last November when he'd given it to me, and not the terrible, bloody, international-terrorists-are-trying-to-kidnap-me part that came right after”

“Trust. We stake our lives on it, but it's a subject that not even the Gallagher Academy can teach. When do you let your guard down? Who do you let in? And I knew at that moment, as I sat beside my mother, bathing in the warm spring light, that those were the questions a good spy never stops asking”
