Observant, passionate, witty, offbeat, Mike Parker tours Powys from the border towns of Hay on Wye, Presteigne and Knighton, through the interior of Rhayader, Llanidloes and Caersws, to the furthest points of Newtown, Penybont, Ystradgynlais and Brecon. He takes the waters at the spa towns Builth, Llandrindod and Llanwrtyd, pauses at the court of Owain Glyndwr and the death scene of Llywellyn the Last, nods to Francis Kilvert and Eric Gill in the Black Mountains, explores ruined Abbey Cwmhir and bustling Newtown, and follows the Heart of Wales railway line, the Roman Sarn Helen road and the rivers Severn and Wye. Could it be that Powys is a time capsule of British life fifty years ago? Is it a stronghold for the Welsh language and culture? What surprises does he stumble upon among the mountains, forests, streams and farms of this mysterious countryside?
