The previous book ended when Earth man Adam Reith and his two companions, barbarian teenager Traz and renegade Dirdirman Ankhe at afram Anacho, captured a shady businessman Woudiver who sold them out to their enemies. Even though Woudiver is their captive, he manages to signal the fourth alien race on the planet, the Pnume, about Reith and arrange his kidnapping. Reith is captured and taken to the vast underground tunnels where the aliens and their human slaves live. He manages to free himself but now has the task of avoiding the Pnume and their human slaves, the Pnumekin, and finding a way to the surface. To do that, he in turn captures a young Pnumekin woman and forces her to show him the way.

This time the book has distinctive two parts: the first part is set in the underground tunnels exploring the Pnumekin culture and the other is set on the surface where Reith must educate the woman about the surface culture. For me, the first part was more fun: I like characters sneaking around and it wasn’t easy to make several chapters of it fun.

The Pnumekin were weird. The Pnume strip them of personality and sexuality with culture and drugs. The woman Reith kidnaps doesn’t even have a name; he calls her Zap 210 based on the area where he found her. Her growth has been stunted with drugs and she has no knowledge of human sexuality or how different genders behave toward each other. She calls it “boisterous conduct” and doesn’t want to even hear about it. Reith must educate her and while he’s considerate enough, I found myself rolling my eyes at the scenes.

The Pnume themselves are curious and collect samples of life, including humans.

Still, this was a good ending to the series, even if the wrap-up was pretty abrupt.
