The Birth of Britain, by Winston S. Churchill. Volume one in his four volume "History of the English-Speaking Peoples". $1.99 as a Nookbook.
Vikings, William the Conqueror, Magna Carta, and all that stuff, in the start of Winston Churchill's huge history set that a Churchill political opponent said should have been titled "Stuff in History that Interested Me"!
