Shattered Sword: The Untold Story of the Battle of Midway by J Parshall and A Tully. It's a really good take on the Battle of Midway and is very well researched from what I can see. The book approaches the battle exclusively from the Japanese point of view, and delves into "Why did the Japanese make x decision instead of y?", which isn't covered nearly as well from Western books.
A lot of mythbusting is also done, correcting common wisdoms such as "If Nagumo hadn't decided to rearm his aircraft with land attack weapons, he'd have been ready to spank the Americans when he found them", and "The torpedo bombers from VT-8 sacrificed themselves for the greater good by pulling Japanese CAP fighters to sea level and thus allow the American dive bombers to attack". By referring to then current IJN doctrine, reconstructed air operations timetables, after action reports and other sources, the authors take apart many of these myths and postulate in their stead more reasonable and likely scenarios, which I found very well done.
The writing style is reasonably relaxed, and I found it to work in the book's favour, making it very enjoyable to read. Highly recommended.

I know there is a method, but all I see is the madness.
