Let's start with the good news. The first thing to note is how well organised the content is. There's a short scene-setting introductory section, dealing with the context just prior to the campaign. This is immediately followed by a comprehensive chronology. This chronology starts with Boney escaping Elba, and runs up to late evening on June 16th, the day of the battle at Quatre Bras. I can see why you'd put a chronology here, but I'd have preferred it after the main body of the text. Either way, it's a usefully succinct reference point.
Before I embark on any critical comments , let's briefly finish the summary of contents. Following the highly detailed coverage of the action itself, we have Aftermath, The Battlefield Today, and Further Reading. One of these last elements that I particularly liked - perhaps in part because I've visited some of the Waterloo battlefield (and will be going again for the 200th anniversary!) - is the section called The Battlefield Today. Having not yet visited either the Quatre Bras or Ligny sites (we did have a nose around Plancenoit, in 2014) these sites have now been added to the 'must do' list! And, of course, Further Reading suggestions are always welcome and useful. So, to summarise my summary of the contents, what's best about this is how well organised the information is, and how much detail there is on the action of the 16th itself.
A reviewer at Amazon's UK website, writing about Corunna by Christopher Hibbert, says 'I'm a huge fan of history, particularly if it's about the Napoleonic wars, but I'm not a huge fan of history books filled with fact after fact and nothing to 'hook' you' (you can read that review here, if interested). I find it hard to say this, especially having followed some exchanges on TMP in which Franklin and another forum member (registered under several different names over an extended period) engage in some quite vitriolic exchanges, but, despite it being a well organised and fact-filled read, I found it rather flat and dull.
