Halfway up, Jane comes to a halt. She is holding onto the rocks very tightly, and seems to be breathing quite fast.

‘Prin?’ she says, and Prin expects her to say she wants to climb back down, that she is too scared to climb all the way to the top, that she wants to go back and just sit on a towel. Prin twists round so she is crouched on the rock looking down at Jane, jelly shoes gripping tight.

‘What is it?’ she asks.

Jane looks up at her, her face like a little monkey’s. Despite the sunscreen, her nose is already growing pink in the sun. ‘Why do they call you that?’ she says. ‘“Prin”. Instead of your name?’

Prin gives her hands a clap. She isn’t holding on at all. ‘It’s a nickname!’ Daddy’s name for her. ‘Short for something – can’t you guess what?’

Jane gazes up at her, her face blank. Just waiting for Prin to tell her the answer. Instead, Prin turns away and scampers up to the top of the cliff. It’s not really a cliff; more just like a little platform. Now that she’s taller, Prin is almost disappointed with how short the jump really is. But she still wants to show Jane – Jane who is still climbing so slowly, one foot, one hand at a time, picking her way up the rocks.

Prin stands up as tall as she can. She can see such a long way from here. She can see Daddy and Mum easily. Daddy is up on one elbow, sort of leaning over Mum. Mum sees Prin and sits up, waving at them: a series of quick, sharp waves. Daddy turns to look over his shoulder. Prin waves back.

She looks down at Jane, who is almost – just about – at the top.

Prin puts her hands on her hips. ‘It’s a nickname,’ she tells her. ‘My daddy’s nickname for me. It’s short for Princess,’ she says, holding out her arms. ‘I’m my daddy’s princess.’

Then she bends her knees, and jumps.

The sand below is so soft to land on, feet and bottom. Like a pillow. Prin falls onto it, still feeling the rush of the fall. Jumping like that, it’s the best feeling in the world: there’s the heat and the sun and the crashing waves and the feeling of soaring, flying.

Prin lies there, staring up into the blue, absorbing it all. She feels giddy with the thrill.

Then she gets to her feet and scampers back up the rock to the top.

It’s Jane’s turn now.

‘Don’t look so scared,’ Prin tells her. They are both standing at the top again now. ‘You saw me do it.’ She tugs Jane’s arm, pulling her closer to the edge. ‘Imagine you have wings. Big, shiny wings. It feels amazing, you’ll love it!’
