Ok, so this is far better than Whatley's 'The Scots and the Union' which was a bland, if informative, guide through the ins and outs of the Union. This book is shorter and to the point: were the Scots bought off in 1707?
This focus is to the book's credit and if you're a Scottish history student writing an essay on it and want an author's opinion the book at least does the gracious thing and takes up a position (which is more than can be said for some rambling histories). The only trouble is that while all the issues Whatley considers are relevant to the central question (the equivalent, English troops at the border, the Aliens Act etc...) the book's main argument is a bit weak, despite taking all the issues into account.
It is not a book which will unite Nationalist and Unionist alike, as I think the blurb states. It is a 19th Century established Unionist perspective which would be fine if only the argument which it was based upon held up to scrutiny (even using the points Whatley raises without any external knowledge!)
Therefore, what you have with this book is a great history source to use in your essays and a really terrific short(ish - but don't let it's length put you off, there's plenty of detail) going over of the main forces upon the Scottish parliamentarians. On the other hand, if you're looking for a general read you won't likely be won over by the argument even if you hold the same mindset. It would've been nice to see the author go in without personal bias but nonetheless a far tighter and more enjoyable book than his 'The Scots and the Union' book.
