"The Long Mynd" takes the idea that magicians can make something out of nothing one step further. The story looks at a world in which a few people can make any physical item they can see clearly in their minds become real. Far from becoming paradise, the modern world collapses as no place becomes safe from atomic bombing. This story picks up with the second generation of "charmers" and follows one young Welshman as he seeks to find a place to live safely.

The story is complete, but it begs to have a sequel since Dafydd fails to find a haven by the end of the book. ( )
