Poor formatting for Kindle, GREAT as a hardback
Format: Kindle
So far I am loving this book, and hating its formatting for the Kindle. Probably because of all the maps and illustrations, it is hard to enjoy on my Kindle, and I have to awkwardly change the size of the page 3-4 times on every page while I try to read it. My guess is I would really love it as a physical book. LATER: As noted I was very disappointed trying to read this on a small Kindle, but the book looked so promising that I repurchased it in hardback. WOW what a difference. Wonderful illustrations, maps, the works. Given the number of important battles chosen, it would not be possible to go into great detail on any single one, but most people are not going to remember all those details anyway, and this book gives you what you really need, and the level of detail you are likely to remember and to help you appreciate the importance of the event. Strongly recommended in hardback.

Great book, the battle descriptions should've been more detailed
Format: Hardcover
The book looks great, both the dust jacket and the book cover are printed with the cover image.
The dust jacket is textured with a matte finish and shiny silver text, while the book cover looks exactly like the front cover image provided here on Amazon (with a glossy finish). In my opinion, the dust jacket looks better.
The book itself looks great. The texts are a bit too short for my taste though, as I would've like to read more detailed descriptions of each battle. Read the sample of the Battle of Marathon that's provided here. It will give you a good idea of the level of detail provided for each battle. Also, some of the battles that didn't get the full 2 page treatment were, in my opinion, significant and were deserving of getting it (Battle of Kadesh for example), while some less significant battles did get it, oddly enough.
All in all, I'd definitely recommend the book, but it does have a few shortcomings mentioned above.
PS. Also, Amazon, please work on your packaging. Add a few of those (styro)foam pieces with the book or something. My book did arrive mostly ok, and mostly unscathed, but when I picked up the package, the book was moving freely inside the banged up package. I'd say I got lucky it didn't get damaged too badly (apart from a few minor impact traces -- I'd say condition it arrived in was 9/10).

Very good book with a few minor flaws
Format: Hardcover
As most books published under the DK banner, this is a visually excellent book that is a pleasure to look at. It is well written and chock-full of outstanding illustrations and maps. I do have a few minor "ding" though. First, I think that the book should have included a "why" the battle changed history. While in most cases, this rationale is included in the text, in a few cases one has to wonder "why" this battle was important; for example, they chose the World War I battle of Verdun, but they also said that the battle was "inconclusive"; if so, how did it change history? Second, I have to question the choice of some of the battles. For example, the editors list "Arnhem", which ended up as a costly allied failure, but fail to mention the wildly successful Soviet "Operation Bagration", which destroyed the German Army Group Center. Third, there were some minor factual inaccuracies. The battles of Passchendaele and Dunkirk were both shown on a map as being located in Northern Italy instead of northern France, while Operation Overlord, the Allied invasion of France, was shown on a map as being more at Pas de Calais vice the beaches of Normandy. In spite of these nits, this is a good book worthy of belonging in you library. Four stars.
