Yeah, apparently it came out in 1994. I would have been 11.
Huh, I don't know what most of those are...
FYI, Cook's Garrett books are a direct play off of the Nero Woolfe detective novels.
Hambly's Dark Novels were somewhat vampiry, somewhat demony.
The rest you pretty much nailed.
Bova's Grand Tour is about man's exploration of our Solar system.
Turtledove's transposition of WW2 into a fantasy realm was stunningly good. Worked in elements buffs would go "YEAH!" over, and his handling of the big issues- the Final Solution, the Bomb, etc.- coheres well with the fantasy setting.
I gotta find time to read the Turtledove stuff. Sounds very interesting.
