Only in Turtledove, are the humans and the real historical events even more fantastic than the Aliens. If you like this series try reading his straight alternate war histories, you will not be disappointed. But back to this book a really gripping read.
Michael B. reviewed Tilting the Balance (Worldwar, Bk 2) on
Really exciting. Harry Turtledove's premise of an alien invasion interrupting WWII leads to all sorts of wild, but logical, consequences. Another thing I like is that the aliens are portrayed as somewhat . . . human (and occasionally a little better!). Remionds me of the best of Star Trek, TNG.
Turtledove is a master historian with an interesting habit of twisting and tweaking history to tell a story - with lessons for our future, and interesting revelations of the past that often have escaped our notice.
