The novel “The Fugitive Worlds” by Bob Shaw was published for the first time in 1989. It’s the third book of the Land and Overland trilogy and follows “The Wooden Spaceships”.

Toller Maraquine II is following in the footsteps of his famous grandfather and has become the captain of an airship but traveling between Land and Overland has become routine or at least it almost always is. The only hope of glory is in Queen Daseene’s will to return to Land to try to repopulate it.

However, those projects must be put aside when a strange object is detected in the sky. Initially, scientists are puzzled because it doesn’t resemble anything that they know but over time it approaches Land and Overland bringing possible dangers. Is the appearance of a kind of barrier between Land and Overland connected to the strange object?
