“It was a nice thing for her to say. In her way. With Greta you have to look out for the nice things buried in the rest of her mean stuff. Greta’s talk is like a geode. Ugly as anything on the outside and for the most part the same on the inside, but every once in a while there’s something that shines through.”

“There was a flicker of something in Greta's look. I couldn't tell whether it was a flicker of love or regret or meanness.”

“I came to a sketch where the space between my arm and Greta’s arm, the shape of the place between us, had been darkened in. The negative space. That’s what Finn called it. He was always trying to get me to understand negative space. And I did. I could understand what he was saying, but it didn’t come naturally to me. I had to be reminded to look for it. To see the stuff that’s there but not there. In this sketch, Finn had colored in the negative space, and I saw that it made a shape that looked like a dog’s head. Or, no—of course, it was a wolf’s head, tilted up, mouth open and howling. It wasn’t obvious or anything. Negative space was kind of like constellations. The kind of thing that had to be brought to your attention. But the way Finn did it was so skillful. It was all in the way Greta’s sleeve draped and the way my shoulder angled in. So perfect. It was almost painful to look at that negative space, because it was so smart. So exactly the kind of thing Finn would think of. I touched my finger to the rough pencil lines, and I wished I could let Finn know that I saw what he’d done. That I knew he’d put that secret animal right between Greta and me.”

“For a long time, all the way through to the end of elementary school, Beans was my only friend. Because that’s how I’ve always been. I only need one good friend to see me through. Most people aren’t like that. Most people are always looking out for more people to know. In the end, Beans was like most people. After a while she had dozens of friends, and by fifth grade it was pretty obvious that even though she was my best friend, I wasn’t hers.”

“I . . . Why do you want me to?” There was a flicker of something in Greta’s look. I couldn’t tell whether it was a flicker of love or regret or meanness, and then she said, “Why wouldn’t I want you to?” Because you hate me, I thought, but I didn’t say it.”

“I didn’t say anything. Greta always knew how to make me lose my words.”

“I stared at Greta’s back. At her matted hair, decorated with brown torn leaves and dirt. What was happening to my sister? What if I’d never come? How long would she have stayed hidden in those cool, damp leaves? How long before she woke up alone and scared, with nothing but the howling of wolves to keep her company?”
