I like WWII non-fiction and my most recent reads/suggestions:
If naval warfare is your preference, the Ian Toll’s Pacific War trilogy might be for you:
Pacific Crucible
The Conquering Tide
Twilight of the Gods
In that order.
Land/tank warfare:
Spearhead by Adam Makos. Soon to be a major motion picture.
Air war:
Masters of the Air by Donald Miller. Soon to be a mini-series in the Band of Brothers/The Pacific tradition, although not HBO this time.
Absolutely first rate reading. I concur and cannot recommend them highly enough.
Additionally, James Hornfischer’s “Pacific Crucible” and “Last Stand of the Tin Can Sailors” are both magnificent.
