The Origins of the British, by Stephen Oppenheimer (http://www.amazon.com/Origins-British-Stephen-Oppenheimer/dp/1845294823/ref=pd_sim_b_6/177-3281845-8440662)
or
Saxons, Vikings, and Celts: The Genetic Roots of Britain and Ireland, by Bryan Sykes (http://www.amazon.com/Saxons-Vikings-Celts-Genetic-Britain/dp/0393330753/ref=pd_sim_b_2/177-3281845-8440662).
At any rate, Oppenheimer also published an essay a couple of years back that is (as far as I can tell) an abridged version of his book:
Myths of British Ancestry (http://www.prospect-magazine.co.uk/article_details.php?id=7817).
