The Land and Overland trilogy is one of Bob Shaw’s most ambitious works. Set on twin planets that orbit close enough to share an atmosphere, the series imagines a civilization that evolved entirely without metals. When a biological threat called the ptertha begins killing people on Land, the population must flee to its sister world by hot-air balloon.
The Ragged Astronauts (1986) introduces this premise and won the BSFA Award. The Wooden Spaceships (1988) and The Fugitive Worlds (1989) continue the story as refugees adapt to Overland and eventually confront the source of the ptertha threat. The trilogy stands out for its inventive world-building and the way Shaw grounds fantastical concepts in practical, physical detail.
