terrible beauty

A big kerangan in the middle of the beautiful river, covered with sands and nice colorful pebbles. If you walk on it, there is this feeling of serenity as you feel the pebbles slowly roll under your feet, moved by your weight. The sand on a hot day becomes hot, soothing to the feet. And if you put your feet in river a few strides away, it's refreshing. You walk again and there's a sharp pain under your sole. When you look, the blood comes dripping from a gaping hole. Where did this terrible beauty come from? Below, a dark green shiny glass lies lurking between the rocks, buried under the sand. It stains from your blood.
