I dropped my bike and plonked down on a patch of grass on the edge of the muddy campsite, trying to catch my breath. The tent was one of those big ones with two rooms and a kitchen tacked on the front. The flaps were all pulled down because of the shimmery rain, with the Parents shut away inside. Dad was always pissed when I interrupted Parent time. But I knew he’d be more pissed if I got blood on my windcheater, so I poked my head ‘round the flap.
