>- Diplomatic Implausibility a Trek novel, which gives us Lt. Worf, newly appointed Federation ambassador to the Klingon Empire. Good, well researched, and consistent with "known" history. Excellent use of tlhIngan Hol - even including a glossary of terms used. Probably not for a non-Trek fan, but it presents interesting new situations with known characters and lots of Trek lore.
- Race to the Moon a history of the Soviet versus American space race. Except... it was really more of a chronicle of the German "space program" and how it ultimately became the USSR vs USA race. Even more it is a history of Von Braun. Not a bad book, but pretty thin on the USSR space program. I suspect if it were written now it would have more detail.
