As a child, Rhianna Pratchett was told of sleeping giants on the hilltops near her grandparents' house in Wales.  
Now she returns to the Welsh mountains and to Cader Idris – a striking mountain in the Eryri National Park – to meet a particularly intriguing giant.  
Rhianna discovers why giants have been important to humans for centuries and asks what giant tales might offer us in the present day.
The fantasy writer continues her trek across an enchanted British Isles to discover mythical creatures that lurk in all corners of the land.
She's out to uncover what they can tell us about our history, our world and our lives today.
