There is something special about the night. For many, just the idea of it conjures thoughts of starlit skies, romance, refuge, of being tucked up in bed. For some, the night means fear, vulnerability, danger, sleeplessness. For others still, nightfall signals the start of work. At night things go bump, monsters hide under beds, owls take wing and foxes prowl.

Overnight is a celebration of all things nocturnal, of those who labour while the rest of us sleep: the bakers, health workers, sailors, couriers, broadcasters, drivers, fishers, the men and women of the emergency services and more. And it is also a hymn to nighttime wildlife, dreams and art. We'll hang out with bats and look at the stars. We'll learn what Moomintroll has to teach us about insomnia. We'll travel by ship, train, racing car and foot. There will be more than one surprise along the way.

Through a series of personal journeys Dan Richards explores what the night means to a fascinating array of people, taking us from night terrors to the glow of watching the dawn break on the summer solstice. Overnight will change the way you think about the hours after dark.
