I've recently been reading a good bit more than I had in quite a while, and have finished a few books and have a couple in progress.
Panzer Commander by Hans von Luck - autobiographical memoir of a man who served under Rommel in France, Africa, and France again. He also served on the Eastern Front and finished up the war near Berlin. Covers his postwar experiences in a Russian prison camp and later in postwar Germany as well.
Is Paris Burning by Larry Collins and Dominique LaPierre - A fairly extensive book with many firsthand accounts, centered around the liberation of Paris in WW2.
Piercing the Darkness by Brock and Bodie Thoene - A fictional novel by two of my favorite authors. This one would likely be classified as a thriller. Many of their other novels are historical fiction, such as Twilight of Courage (of which I frequently re-read various sections).
With Rommel in the Desert by H.W. Schmidt - another autobiographical Afrika Korps memoir. The author served in various positions under Rommel, from combat commands to a time as Rommel's personal assistant.
Bread and Wine by Ignazio Silone - a novel focused on the Italian resistance fighters in WW2.
Alamo in the Ardennes by John C. McManus - As might be guessed from the title, this one is focused on the Battle of the Bulge, with a concentration on telling many small personal experiences from various participants.
