“A breath of sound across the landing, almost imperceptible, like a shadow moving against blackness; then nothing.”

“She was like a reprieve; like Eurydice, gifted back to Orpheus from the darkness for a brief miraculous moment. I wanted, so intensely it took my breath away, to reach out and lay a hand on her soft dark head, to pull her tightly against me and feel her slight and warm and breathing, as if by protecting her hard enough I could somehow undo time and protect Katy, too.”

“...and our footsteps rang and echoed till it sounded like the room was full of dancers, the house calling up all the people who had danced here across centuries of spring evenings, gallant girls seeing gallant boys off to war, old men and women straight-backed while outside their world disintegrated and the new one battered at their doors, all of them bruised and all of them laughing, welcoming us into their long lineage.”

“And God the taste of undercover on my tongue again, the brush of it down the little hairs on my arms. I'd thought I remembered what it was like, every detail, but I'd been wrong: memories are nothing, soft as gauze against the ruthless razor-fineness of that edge, beautiful and lethal, one tiny slip and it'll slice to the bone.”

“We lay side by side on the extension roof, hands behind our heads, elbows just touching. My head was still spinning a little, not unpleasantly, from the dancing and the wine. The breeze was warm across my face, and even through the city lights I could see constellations: the Big Dipper, Orion's Belt. The pine tree at the bottom of the garden rustled like the sea, ceaselessly. For a moment I felt as if the universe had turned upside down and we were falling softly into an enormous black bowl of stars and nocturne, and I knew, beyond any doubt, that everything was going to be all right.”

“It took my breath away, that evening. If you've ever dreamed that you walked into your best-loved book or film or TV program, then maybe you've got some idea how it felt: things coming alive around you, strange and new and utterly familiar at the same time; the catch in your heartbeat as you move through the rooms that had such a vivid untouchable life in your mind, as your feet actually touch the carpet, as you breathe the air; the odd, secret glow of warmth as these people you've been watching for so long, from so far away, open their circle and sweep you into it.”

“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.”
