In High Places, Tor, 2006, is the third novel in Harry Turtledove's Crosstime Traffic series of alternate history and science fiction. It follows the adventures of Annette Klein, who is traveling through a world in which the 14th century Black Plague wiped out a greater percentage of the European population than in OTL. As a result, Southern Europe is under Muslim rule, and Northern Europe is a relative backwater. Christianity has shifted dramatically thanks to the arrival of "God's Second Son", Henri.
On a journey from the Kingdom of Versailles to Marseille with her parents along with a local named Jacques, Annette and Jacques are captured by slavers and separated from the caravan. The two are taken to an even more primitive alternate by renegade Crosstimers who use the Crosstime technology to run a slaving world.
The novel details Klein's attempts to escape back to her home timeline to unmask the illegal activities.
- "Islands in the Sea", which also depicts a world where Islam is outpacing Christianity in Europe. The POD is the result of a military reversal in the 8th century.
- Through Darkest Europe depicts a world where the Islamic world is more progressive and enlightened than Christian Europe, with the POD being a series of philosophical "reversals" in the 12th and 13th centuries.
