A very useful introduction to Tudor Britain, especially as it treats Scotland and the important contribution of the Scottish Reformation with the weight it deserves.
The focus of the book is on the politics of religion which dominated the 16th century but it also includes social and cultural aspects and considers the change of focus from separate European kingdoms to a more united 'British' state.
I found the discussion of English Puritanism particularly helpful - especially as it was framed within a comparison of events north of the Border, a vital context lacking in many other works.
There is also a very useful guide to further reading for those who want to know even more. Pleasingly, most of the works listed are of very recent vintage - Dr Ryrie is clearly a man with his finger on the pulse about the latest research.
All in all I would heartily recommend this as a first port of call for anyone new to the subject - whether A-level students, undergraduates or simply those whose interest has been stimulated by 'The Tudors'!
