For a great, and very readable, introduction to the end of the Roman Republic I'd very much recommend Rubicon by Tom Holland. He has the knowledge and weaves a fantastic narrative. This is possibly my favourite narrative History book of all time. I guess this should really be about books relating to British History? ... There is some in there.'The Strange Death of Liberal England' by George Dangerfield is a fantastic curiosity if you can get it'The confident hope of a miracle' by Neil Hanson is a brilliant read about the spanish Armada.'Civil War' by Trevor Royle is a cracking account of the English Civil War.
