It turns out that Golan Trevitz is not satisfied with the way he turned the history of the Galaxy (the novel “Community on the Edge”). The young man goes in search of the final answer to the final question, and drags with him his faithful comrade, the armchair scientist Yanov Pelorat - of course, along with the beautiful Gaian Bliss, who will not allow a hair to fall from his bald head. Unexpected discoveries about the past and prospects of humanity await friends, and with this Isaac Asimov will put an end to his chronicle of the future; new volumes of the saga will cover only the prehistory of psychohistory and Communities.
