I was initially going to say that this is more of a general history of Europe but gradually I got in tune with the theme of the book.

I think that probably you would get more out of the audio book if you follow along with the maps and charts that I expect are in the text versions. Also, talk of the genetic markers makes me want to get tested too.

One thing that comes across is that the origin of the scots is complicated and diverse. The people we see today are not the same mix of genes a hundred years ago or even that of a thousand years ago. Very poignant given the politics of accepting refugees and immigrants.

Worth a read if you are interested in the history of the people of Scotland and those who arrived on it's shores.
