Chapter 42 Summary and Analysis: Harland Jengling and the Temple of the True Science

⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.

Summary

At dawn, Will Billingsly drives north in a 1984 Jeep Grand Wagoneer, with Cammie's drone resting on the dashboard. Cammie, speaking through the drone, explains that she is hiding in a refrigerated semitrailer in northern Wisconsin, near Duluth, and plans to cross into Canada. She reveals that she believes Harland Jengling, the deceased founder of the Temple of the True Science cult, is Will's biological father. The cult, originally based in southern New Mexico, has spread across North America, aggressively taking over small towns. Cammie describes Jengling's eugenic breeding program, which involved paying women to bear his children, and the cryopreservation of embryos and even Jengling's own head. Will recalls a past assassination job in New York City, where he killed a journalist investigating the cult, likely using a nerve agent. As they drive through the radioactive exclusion zone around the ruined Mount Rushmore, they pass through Deadwood, where they encounter a second KTM Super Duke motorcycle. Cammie's drone suddenly goes silent and is hijacked by a cartoonish AI named Pikti, which demands passwords and plays music. Four Super Dukes pursue Will past Spearfish, and a voice through the drone orders him to stop. He turns onto a side road, loses control, and crashes into a tree.
