Book number four of a five book science fiction series.  I reread the well printed and well bound MMPB published by Baen in 1996 that I bought used on Amazon since I could not get a new copy, being out of print.  I have read all five books in the series.  The series is probably finished as the author has moved onto several new series.
On a parallel universe Earth, it is the year 2442 AD.  On this Earth, Europe lost WWII to the Drakons who used atomic weapons on all of the capitols.  Then World War III occurred in 1999 between the massively bioengineered Homo Drakonsis and the Homo Sapiens.  The Homo Drakonsis won and carefully bioengineered the Homo Sapiens into Homo Servus. Earth has less than a half billion population now with most industries in space scattered around the Solar System.
In an FTL (faster than light) gateway experiment gone wrong, a 400 year old female Drakon is transported to our universe and Earth in the year 1995 AD.  She lands in New York City, takes her bearings, and sets out to build a gateway back to her Earth so that the Drakon can invade and convert our Earth to look like her Earth with the Domination.  After all, her 200+ IQ and warrior skills enable her to find scientists and lead them also.  But, a colony of Homo Sapiens from Alpha Centauri detect the interuniverse wormhole and send an agent to follow her.
