But in the real world, you couldnt really just split a family down the middle, mom on one side, dad the other, with the child equally divided between. It was like when you ripped a piece of paper into two: no matter how you tried, the seams never fit exactly right again. It was what you couldn't see, those tiniest of pieces, that were lost in the severing, and their absence kept everything from being complete.

The lizard stared up at us, and we stared back, taking each other in. He was little and defenseless, I felt sorry for him already. This was a screwed-up place he'd just come into. But he didn't have to know that. Not yet, anyway. There in that room, where it was hot and cramped, the world probably still seemed small enough to manage.

When he first put his arms around me, it was tentative, like maybe he expected I'd pull away. When I didn't, he moved in closer, his hands smoothing over my shoulders, and in my mind I saw myself retreating a million times when people tried to do this same thing: my sister or my mother, pulling back and into myself, tucking everything out of sight, where only I knew where to find it. This time, though, I gave in. I let Wes pull me against him, pressing my head against his chest, where I could feel his heart beating, steady and true.

So much had happened that morning. Yet it was this image, this moment, that i kept going back to hours later, after we'd made it safely to the walkway and gone our separate ways to classes. How it felt to have the world moving beneath me, a hand gripping mine, knowing if i fell, at least i wouldn't do it alone.

The basic fact is that no, this isn't ideal. Very few things are. Sometimes, you have to manufacture your own history. Give fate a push,so to speak.

Maybe it was true, and being a girl could be about interest rates and skinny jeans, riding bikes and wearing pink. Not about any one thing, but everything.

I hoped that Grace would be a little bit of the best of all of us: Scarlett's spirit, and my mother's strength, Marion's determination, and Michael's sly humor. I wasn't sure what I could give, not just yet. But I would know when I told her about the comet, years from now, I would know. And I would lean close to her ear, saying the words no one else could hear, explaining it all. The language of solace and comets, and the girls we all become, in the end.
