Mel is quite comfortable sitting up here right now, one leg hanging relaxed on the grassy side of the wall, the other up on the top edge, taking her weight completely on the ball, knee soft and bent.

She watches Rachel disappear, then her vision pulls out a little to watch the wind moving in the grass.

"RACH."

She hollers out the name, quick and urgent, at the same time as her bent leg snaps out and she rolls off the wall, throwing herself into a dive, straight into the sea of corn.
