On a windswept stretch of the Durham coastline, there's treasure to be found: jewels of shining sea glass, swept in by the tide after years at sea. Gathered together in a jar on the windowsill, each seaworn pebble is a moment in time, a glinting archive of unknowable lives.

Seaglass is a collection of such moments; essays blending creative non-fiction with nature writing and memoir, and portraying with powerful observation and moving honesty the journey of a young woman navigating modern adulthood. The stories draw a map of Kathryn's life, from Manchester to the South Wales coastline and out to the Thousand Islands in Canada's Saint Lawrence River. Traversing wilderness, natural history, travel and water – rivers, lakes, coastlines and leisure centres – Seaglass explores shared experiences, anxieties, confidence and contentment.
