I thought this the weakest of Ms. Norton's Time Travel Series that I've read so far.

The story involves Western Agents, whose minds (through technology) have been reverting back to their Apache cultural past, along with Red Agents (presumably the USSR and China) and their Mongolian "mind slaves." The Reds have also used a technology (it appears the same on Western Agents are using) for the Mongols to operate with their cultural past mindset. The reason for the culture linking technology is to prepare time travel agents to go back into time. The Reds though also have a technology that turns the Mongols into obedient slaves.

The plot centers on the Western Agents preventing the Reds from acquiring advanced alien technology. The story is mostly a lot of action and not much insight (not my formula for good reading. The book doesn't describe any new races or cultures (that haven't already been described by other books of the series.) It does compare and contrast the cultures of the Apache and the Mongol. Unfortunately the book doesn't develop this the way it could have. ( )

Apache v. Tartar! In space! And there are Reds, and coyotes! And some time travel, though mostly mental, oh my goodness Norton how I adore you. ( )
