“It’s bright pinky-white sand was made entirely of shell dust, like star dust, among which, if you sifted it with your fingers, were infant shells as small as the grains but perfectly shaped. Scattered over the surface were larger shells of many kinds and shapes, some as delicate as flower petals, others, though small, built to withstand any battering sea.”
