The premise is deceptively simple. One day in 2015 the instructions for building a Stepper box appear online, and humanity spreads across an infinite series of parallel Earths, most of them uninhabited and rich with resources. The question the series really asks is what happens to human societies, economies, and identity when there is suddenly no shortage of space.
Pratchett and Baxter divide the workload in a way that plays to both their strengths. The human characters feel distinctly Pratchettian, warm and flawed and funny. The science and the cosmic scale are unmistakably Baxter. The collaboration produced something neither would have written alone, and the five books vary in tone while maintaining a coherent world.
The series was completed after Pratchett’s death in 2015, with the final volume published posthumously from work both authors had prepared together.
