The Time Wanderers

The Time Wanderers (original Russian title: "Волны гасят ветер", lit. "Waves Silence the Wind") is the tenth and unfortunately final novel by the Strugatsky Brothers to be set in the Noon Universe.

Events and characters from virtually all preceding Noon Universe novels come together as the 22nd century ends and the Wanderers' plot finally comes to fruition.

Tropes found in the novel:

 * Fictional Document: About half of the book consists of multiple Fictional Documents.
 * Secret Test of Character: A global scale Secret Test of Character, no less.
 * Transhuman Aliens / Human Subspecies : The "Homo Ludens".
