'We spend most of our waking lives staring at bright lights, ignoring the half-lit and shadowed spaces surrounding us. We pay little attention to dawn and dusk, that band of half light that constantly moves across the surface of the earth, in some places lasting only a few minutes, in others weeks. This time of transformation has been the source of countless human rituals, providing roots for our sense of mystery and spirituality ...' Two Lights is extraordinary debut from new nature writer, interweaving landscape, wildlife and travel writing as well as science and memoir.
