A fascinating book about the genetic history of the British Isles as seen through our mitochondrial DNA and Y-chromosomes. The author spends a long time talking about our history as seen through fable, story and oral history, the kind of thing you might think was just pie in the sky made up by our ancestors to sound good (or bad as desired). I found these history lessons a little longwinded but it was enthralling when they were linked up with the evidence from our genes.
