Moonlight, starlight, the ethereal glow of snow in winter. When you flick off a switch, other forms of light begin to reveal themselves. Artificial light is everywhere. Not only is it damaging to humans and to wildlife, disrupting our natural rhythms, but it obliterates the subtler lights that have guided us for millennia. In this beautifully written exploration of the power of light, Matt Gaw ventures forth into darkness to find out exactly what we're missing: walking by the light of the moon in Suffolk and under the scattered buckshot of starlight in Scotland; braving the darkest depths of Dartmoor; investigating the glare of 24/7 London and the suburban sprawl of Bury St Edmunds; and, finally, rediscovering a sense of the sublime on the Isle of Coll. Under the Stars is an inspirational and immersive call to reconnect with the natural world, showing how we only need to step outside to find that, in darkness, the world lights up.
