I recently saw this wonderful illustration of Yorkshire Megaliths. I contacted the author, Adam Morgan Ibbotson, and he kindly sent me a copy.
I was rather chuffed, Adam wrote one of my favourite books of 2021, Cumbria’s Prehistoric Monuments. It’s a lovely book, comprehensive, very readable with beautiful photographs, maps and illustrations. If prehistory and big old stones are your thing, you’ll love this. You can buy it here
