Aragorn, re: US Army in the Pacific, if you are referring to the first vol of John McManus's trilogy, it is a bit dry, and frankly, the events of much of the 41-43 time frame have been covered very well by others, with more detail. However, other than having, in my opinion, insufficient maps, the 2nd and 3rd volumes are pretty good.
I do recall you mentioning, I think, several years ago that doorstoppers aren't your favorite.
