Hitler's Greatest Defeat by Paul Adair

This refers to Operation Bagration, the Soviet Summer Offensive that began on June 22, 1944. We in the West focus primarily on DDay as the major military event of Summer '44, but it was Bagration that really did in the Wehrmacht, which saw 30 divisions destroyed in the matter of a few weeks.  This book is a concise, quick read on the subject.

Suicide of the West by James Burnham

Conservative classic written in the early 60's that I finally got around to reading.
