“I know that small-town silence, I'd run into it before, intangible as smoke and solid as stone. We honed it on the British for centuries and it's ingrained, the instinct for a place to close up like a fist when the police come knocking. Sometimes it means nothing more than that; but it's a powerful thing, that silence, dark and tricky and lawless. It still hides bones buried somewhere in the hills, arsenals cached in pigsties. The British underestimated it, fell for the practiced half-witted looks, but I knew and Sam knew: it's dangerous.”

“... I stayed because running seemed too strange and too complicated. All I knew was how to fall back, find a patch of solid ground, and then dig my heels in and fight to start over.”

“Frank told me once--and I don't know whether he's right or not, and I didn't tell Sam this either--that all the best undercovers have a dark thread woven into them, somewhere.”

“I was never afraid of getting killed and I was never afraid of losing my nerve. My kind of courage holds up best under fire; it's different dangers, more refined and insidious ones, that shake me.”

“My friend Emma, who likes things to add up neatly, claims that this is because my parents died when I was too young to take it in: they were there one day and gone the next, crashing through that fence so hard and fast they left it splintered for good. When I was Lexie Madison for eight months she turned into a real person to me, a sister I lost or left behind on the way; a shadow somewhere inside me, like the shadows of vanishing twins that show up on people's X-rays once in a blue moon. Even before she came back to find me I knew I owed her something, for being the one who lived.”

“I had learned early to assume something dark and lethal hidden at the heart of anything I loved. When I couldn't find it, I responded, bewildered and wary, in the only way I knew how: by planting it there myself.”

“Most people have no reason to know how memory can turn rogue and feral, becoming a force of its own and one to be reckoned with. Losing a chunk of your memory is a tricky thing, a deep-sea quake triggering shifts and upheavals too far distant from the epicenter to be easily predictable.”
