“One afternoon, as Rose lay in a sweaty daze, teetering on the edge of consciousness, she made me swear that I would look after Linden, and I promised I would. I didn't expect to keep that promise, but maybe my,lie will at least do him some good in the meantime.”

“And then I wonder, does my brother think of me this way? We entered this world together, one after the other, beats in a pulse. But I will be first to leave it. That's what I've been promised. When we were children, did he dare to imagine an empty space beside him where I then stood giggling, blowing soap bubbles through my fingers? When I die, will he be sorry that he loved me? Sorry that we were twins? Maybe he already is.”

“Linden just wants to protect her, is what I want to say. She's all he has. I left him. I'm at arms reach, but I've left him.”

“He looks at me, and I don't know what he sees. I used to think it was Rose. But she's not here with us now, in this room. It's just him and me, and the books. I feel like our lives are in those books. I feel like all the words on the pages are for us.”

“I don’t look away, because she’s right: I betrayed her, and I’m not sorry. To keep her safe, I would betray a thousand kingdoms.”

“I wonder if she has figured out that I'll never love Linden, especially not in the way she does, and that he'll never love anyone the way he loves her. I wonder if she realizes, despite all her efforts to train me, that I can never take her place.”

“My uncle used to let me pretend they were bricks," Linden says, startling me. He eases a thick hardcover from the shelf, hefts it in either hand, and then places it back. "I like to build houses out of them. They never came out exactly like I'd planned, but that's good. It taught me that there are three versions of things: the one I see in my mind, and the one that carries onto the paper, and then what it ultimately becomes."For some reason I'm finding it difficult to meet his eyes. I nod at one of the lower shelves and say, "Maybe it's because in your mind you don't have to worry about building materials. So you're not as limited.""That's astute," he says. He pauses. "You've always been astute about things.”
