In High Places (2006) is the third novel in the Crosstime Traffic series, following Curious Notions. Annette Klein has spent the past year as Khadija, a muslim girl, in an alternate timeline. She is presently living with her parents in Paris within the Kingdom of Versailles, but will soon be returning to Marseilles and then to her home timeline. She is very happy to be returning to civilization.
In this novel, Jacques is a guardsman in the service of Duke Raoul. Jacques has met the Kleins in their identity of Muhammad al-Marsawi and family and was attracted by Annette, although the robe and veil hid all but her hands and eyes. He though she was about his own age, but he couldn't really be certain. Muhammad had aroused Duke Raoul's curiosity for various reasons, including his perfect Parisian accent; now Jacques is working as a caravan guard while spying on Annette's family.
South of Grenoble, brigands ambush the caravan, taking captives and looting the pack animals. Annette reacts to a lunging attack with a Judo throw and also to the next and the next, but then somebody hits her on the side of the head and she goes down. After another blow to the head, she loses consciousness. Jacques is shot in the leg as he runs back to the Kleins and then surrenders to the brigands.
When Annette regains consciousness, she finds that Jacques is still with her on their way to Madrid. But her parents had been taken to Marseilles. Arriving in Madrid, they are both sold to the same master and follow him to a compound within the city.
That evening they are taken down to a subcellar, placed against the wall, and see a silvery box suddenly appear in the center of the chamber. Annette immediately recognizes the box as a transposition chamber and knows that the slavers have access to crosstime technology. Soon she realizes that the technology must have been acquired within her own homeline; someone in Crosstime Traffic is running the whole show.
This novel portrays the ultimate nightmare of the Crosstime Secret: rogue employees using alternate timelines to act out their own frustrated perversions. The outlaws have taken slaves from various timelines and used them like animals. Even worse, some people have paid to be treated as such slaves, abused and beaten into submission. Of course, none of the paying customers are intentionally killed, but nothing keeps the guards from killing the real slaves.
This subject is addressed in Piper's Paratime series, but never covered to this extent. The characterization is much better developed herein, particularly among the technologically primitive slaves. Also, Annette and Jacques learn much about themselves and their cultures from such close contact with both the slavers and the slaves.
One of the things that Annette learns is the need for slaves (or the equivalent) in low technology cultures. All kinds of necessary work must be done by unwilling individuals if labor saving machines are not available. Insofar as the reviewer is aware, such work was performed involuntarily in all such low technology cultures, from the Norse thralls to the Chinese peasants. Such servitude -- from indentured servants to chattel slaves -- was common into the nineteenth century and, despite all efforts to eradicate it, still occurs elsewhere in the world.
Highly recommended for Turtledove fans and for anyone else who enjoys tales of high adventure and alien cultures.
