The novel Crashlander combines the short stories featuring the space pilot Beowulf Shaeffer "Neutron Star" (1966), "At the Core" (1966), "Flatlander" (1967), "Grendel" (1968), "The Borderland of Sol" (1975), and "Procrustes" (1993).
The stories are linked, and some of them extended, by a framing story titled "Ghost". This story recounts Shaeffer's reunion with a ghostwriter whom Shaeffer had used to write about his adventures at the neutron star and at the core, Anders Smittarasheed. Anders, working for ARM agent Sigmund Ausfaller, has come to question him about his dealings with Pierson's Puppeteers, General Products and Carlos Wu, as well as what happened to Wu and ARM agent Feather Filip. Wu, Shaeffer and Sharrol Janss and their children, Tanya and Louis Wu, had secretly emigrated from Earth to the planet Fafnir to escape the control of Earth's United Nations government and the ARM.
This novel provides examples of:
- Framing Device: "Ghost" is an external story that serves the purpose of connecting six short stories into one.
- I Just Want to Be Normal: Beowulf Shaeffer didn't want to be a hero, but he found himself being put in extraordinary circumstances anyway.
- Patchwork Story: Larry Niven's "novels" Flatlander and Crashlander are actually his Gil "The Arm" Hamilton stories and Beowulf Schaeffer stories (respectively) collected together and given an external story to fit into.
