The Last Convertible by Anton MyrerA "great" American novel about the "Greatest" Generation, but it's mostly about people with poor communication skills making poor decisions. I made it through the war, but stopped reading shortly thereafter.
Worlds For The Taking by Kenneth BulmerHonestly, a lot of the reason I bought this was because of the use of the Function Display font on the cover (which Ace used occasionally in the 60s). A rather disturbing take on colonialism, with planets literally getting stolen and moved by the Terran Corps. Also prey to more-than-the-usual foibles of its era; I think I set the book down shortly after, in the middle of a firefight when allies are dying all around him, one of the POV characters takes a moment to sexually harass his communications officer.
The Enchantment Emporium by Tanya HuffI love Huff's work, but the starting premise of this book involved generations of people being mind-controlled into forced sex, and I'm not spending any more time with that.
