Dawn and dusk – those fleeting, half-lit hours – are when the ordinary becomes extraordinary. In THE SECRET WORLD OF TWILIGHT, author and smallholder Sally Coulthard invites us into this magical in-between realm, where seductive night-blooming flowers open, secretive mammals stir, giant moths reign and fantastical sea creatures ride the tide. Blending natural history, folklore and memoir, Coulthard reveals twilight as a vital, liminal force: one that has inspired awe for millennia and still has the power to illuminate our daily lives.

From the Great Salt Lake to the Aral Sea, across the American West and around the world, the unusual beauty of these shimmering, uncanny bodies of water captured her imagination.
