They come back to school for fourth year in the rain, thick clammy rain that leaves your skin splashed with sticky residue. The summer was weird, disjointed: someone was always away on holiday with her parents, someone else always had a family barbecue or a dentist appointment or whatever, and somehow the four of them have barely seen each other since June. Selena’s mum has taken her to have her new short hair cut properly – it makes her look older and sophisticated, till you get a proper look at her face. Julia has a hickey on her neck; she doesn’t tell, and none of them ask. Becca has shot up about three inches and got her braces off. Holly feels like she’s the only one who’s still the same: a little taller, a little more shape to her legs, but basically just her. For a dizzy second, standing with her bag dragging at her shoulder in the doorway of the Windex-smelling room they’ll be sharing this year, she’s almost shy of the others.

None of them mention the vow. None of them mention getting out at night, not to talk about how cool it was, not to suggest they could find a new way. One tiny corner of Holly starts to wonder if for the others it was one big joke, just a way of making school or themselves more interesting; if she made a tool of herself, believing it mattered.

Chris Harper has been dead for three and a half months. No one mentions him; not them, not anyone. No one wants to be the first, and after a few days it’s too late.

A couple of weeks into term the rain lets up a little, and on a restless afternoon the four of them can’t face another hour of the Court. They slip on their innocent faces and drift round the back, into the Field.

The weeds are higher and stronger than last year; rock-slides have taken down the heaps of rubble where people used to perch, turned them into useless knee-high jumbles. The wind scrapes chicken wire against concrete.

No one’s there, not even the emos. Julia kicks her way through the undergrowth and settles with her back against what’s left of a rubble-heap. The others follow her.

Julia pulls out her phone and starts texting someone; Becca arranges pebbles in neat swirls on a patch of bare earth. Selena gazes at the sky like it’s hypnotised her. A leftover spit of rain hits her on the cheekbone, but she doesn’t blink.

It’s chillier here than round the front, a wild countryside chill that reminds you there are mountains on the horizon, not that far away. Holly shoves her hands deep in her jacket pockets. She feels like she’s itchy, but she can’t tell where.
