Orbitsville Departure by Bob Shaw
The novel “Orbitsville Departure” by Bob Shaw was published for the first time in 1983. It’s the second novel of the Orbitsville series and is the sequel to “Orbitsville”.
Two centuries after the discovery of Orbitsville, most of humanity has spread in its vast spaces. Garry Dallen is working on an Earth now sparsely populated but where crime still exists. When the minds of his wife and his son are destroyed by a weapon whose effects are worse than death, his quest of the perpetrator brings him to Orbitsville.
Gerald Mathieu wants to destroy the evidence of his crimes but ends up destroying Garry Dallen’s family. No one seems to suspect him but somehow the two of them continue to cross path. Going on Orbitsville doesn’t seem the solution either, also because suddenly the immense sphere seems to start showing signs of activity.
