e were seven when Nat decided that she wanted to be a model.

“Gosh,” somebody’s mum said at a school disco. “Natalie. You’re getting gorgeous. Maybe you could be a model when you grow up.”

I paused from filling my party dress pockets with chocolate cake and jelly sweets. “A model of what?” I asked curiously. And then my greedy little hand went out to grab a mini jam roll. “I have a model airplane,” I added proudly.

The mum gave me the look that I was already used to by then.

“A model,” she explained, looking at Nat, “is a girl or a boy who gets paid ridiculous quantities of money to wear clothes they don’t own and have their photo taken.” I looked at Nat and already I could see her eyes starting to glow: the seed of the dream being planted. “Just hope you grow tall and thin,” the mum added bitterly, “because if you ask me, they all look like aliens.”

At which point Nat put her chocolate cake down and spent the rest of the night sitting on the floor, with me pulling on her feet to make her legs longer.

And I spent the rest of the night talking about space travel.

It’s finally here.

Eight years of buying Vogue and not eating pudding (Nat, not me: I eat hers) and we’ve finally made it to the very edge of Nat’s destiny. I feel a bit like Sam in The Lord of the Rings, just before Frodo throws the ring into the fires of Mount Doom. Except in a more positive, magical way. With slightly less hairy feet.

Nat doesn’t look as excited as I thought she would. She looks terrified and as stiff as a board standing, totally still, in the middle of the NEC entrance. She’s staring at the crowd as if it’s a pond full of fish and she’s a really hungry cat, and – honestly – I’m not even sure she’s breathing. I’m tempted to put my head on her chest just to check.

The thing is: she’s doing it all wrong.

I know a lot about stories and magic – thanks to reading loads of books and also belonging to a forum on the internet – and the most basic rule is that it has to come as a surprise. Nobody hopped into a wardrobe to find Narnia; they hopped in, thinking it was just a wardrobe. They didn’t climb up the Faraway Tree, knowing it was a Faraway Tree; they thought it was just a really big tree. Harry Potter thought he was a normal boy; Mary Poppins was supposed to be a regular nanny.

It’s the first and only rule. Magic comes when you’re not looking for it.

But Nat’s looking for it, and the harder she looks, the less likely it is to turn up. She’s scaring the fashion magic off with her knowing, waiting vibes.

“Come on,” I say, trying to distract her by pulling at her (or technically my) coat sleeve. I need to get her to think about something else so that the magic can do its thing. “Let’s just go and shop, OK?”

“Mmm.”

I don’t think she can even hear me any more. “Look!” I say enthusiastically, pulling her to the nearest stall. “Nat, look! Handbags! Shoes! Hair bobbles!”

Nat gives me a distracted glance. “You’re dragging my coat on the floor.”

“Oh.” I bundle it back under my arm and start tugging Nat towards the next stall.

“What do you think?” I say, picking up a small blue sequined hat and plopping it on my head. When we were little, we’d spend hours and hours in department stores, trying on different hats and pretending we were going to a royal wedding.

“Uh-huh.” Nat gets a little bit more tense and looks over her shoulder.

“Come on, what about this one?” I pick up a large floppy hat covered in big pink flowers and put it on. “Look.” I wiggle my bottom at her.

Nat abruptly whips round. “Oh my God,” she whispers and it takes me a few seconds to realise that it has nothing at all to do with my bottom.

“Have you seen one?”

“I think so!” She looks again. “Yes, I think I can definitely see an agent!”

I peer into the crowd, but I can’t see anything. They must be like fairies: you can only see them when they want you to.

 

“Stay right here, Harriet,” Nat whispers urgently. She starts moving into the crowds. “Don’t move a muscle. I’ll be back in a second.”

Now I’m confused. “But…” This makes no sense. “Don’t you need me with you?” I call after her. “Isn’t that why I’m here? For support?”

“In spirit will do just fine, Harriet,” Nat shouts back. “Love you!”

And then she disappears completely.
