Cathy’s debut work of non-fiction, The Fullness of Time (Bloomsbury, 2026), is a journey into the forgotten art of marking time through signs in the world around us – from the slow sliding of sunbeams to the wheeling of the stars. Past generations would tell time by shadows shrinking, the midday glow over a mountaintop, the crowing of the rooster in the darkness. They noticed the flowers that close at noon, sensed how the quality of light changes at dusk, and marked time at night by the motion of the stars. Today, in our clock-bound, screen-immersed world, most of us rely on machines to mark the hours. But what riches might we gain from reclaiming the forgotten art of sensing time by events in the living world?
