Britain's landscape is scarred with haunting and romantic remains; these shadowlands that were once filled with life are now just spectral echoes. Peering through the cracks of history, we find Dunwich, a medieval city plunged off a Suffolk cliff by sea storms; the lost city of Trellech unearthed by moles in the Welsh Marches; and the ghostly reservoir that is Capel Celyn, one of the few remaining solely Welsh-speaking villages, drowned by Liverpool City Council.

Historian Matthew Green tells the extraordinary stories of how these places met their fate and probes the disappearances to explain why Britain looks the way it does today. Travelling across Britain, Green transports the listener to these places as they teeter on the brink of oblivion, vividly capturing the sounds of the sea clawing away row upon row of houses, the taste of medieval wine, or the sights of puffin hunting on the tallest cliffs in the country. We experience them in their prime, look on at their destruction and revisit their lingering remains later as they are mourned by evictees and reimagined by artists, writers and mavericks.

By exploring the lost causes and dead ends of history - places lost to natural phenomena, war and plague, economic shifts and technological progress - the precariousness of our own towns and cities, of humanity, becomes clear. Shadowlands is a deeply evocative and dazzlingly original account of Britain's past.
