“The alien library discovered in the previous novel proved to have locations of many unknown worlds. Finding the secure location of planet Topaz compromised, Apache operatives, including Travis Fox, are sent on an emergency trip by a mind-altering machine, Redax, that crash lands. They discover they have the ability to communicate with the native coyotes, but have no idea why they are there. They encounter Russians who have undergone similar treatment, and similarly lacking their memories, who were taken from the days of the Mongolian Golden Horde.” ~ Wikipedia
