Sometimes if you want something badly enough, you can make it happen. If you miss someone so desperately that it wrecks your insides, you say their name over and over until you conjure then. It's called sympathetic magic and you just have to believe in it to make it work.

The inside of the door is glossy white. A total re-paint. I touch it with my fingers, but it stays the same. It's so bright it makes the room waver at the edges. Every few years we disappear.

How late is it? How long have we been sitting here? I look at my watch – three thirty and the day is almost ending. It’s October. All those kids recently returned to classrooms with new bags and pencil cases will be looking forward to half term already. How quickly it goes. Halloween soon, then firework night. Christmas. Spring. Easter. Then there’s my birthday in May. I’ll be seventeen. How long can I stave it off? I don’t know. All I know is that I have two choices – stay wrapped in blankets and get on with dying, or get the list back together and get on with living.

Maybe I’ll come back as somebody else. I’ll be the wild-haired girl Adam meets in his first week at university. ‘Hi, are you on the horticultural course as well?

I feel something very small growing inside me as I look at her, and I realize in one absolutely clear moment that I don't like her at all. 'You know what?' I say. 'Forget it. I'll do the list by myself.' She stands up, swings her stupid hair about and tries to look offended. It's a trick that works with guys, but it makes no difference to the way I feel about her.

I'm here, Tess. I'm right here, holding your hand. Adam's here, too, he's sitting on the other side of the bed. And Cal. Mum's on her way, she'll be just a minute. We all love you, Tessa. We're all right here with you.
