I try to stay on top of books about the Pacific war or aspects thereof, and ran across this one recently. It's by the author of Six Frigates (which I am reading now, and is an overview of the first six months of the Pacific war, from Pearl Harbor to Midway.
There's really not much new here, and while the author provides a lot of useful background (principally about prewar Japan) that I didn't know, for the most part, it's a story that's been told before, although it benefits greatly from the new scholarship in Shattered Sword, which first provided empirical data showing that the the Japanese carriers at Midway were not as invincible as previously thought.
Overall a good read, but I'm still a little uncertain why Toll felt this book needed writing. You could (and I did) watch Pearl Harbor and Midway back to back and get pretty much the story.
