The duology “Realized Probability” (the first book is “Newcomer from Nowhere”, the second is “The Young Wolves Return”) tells about contacts and conflicts of two polar worlds - the world of humanist confederates and the world of savage imperialists. Both main characters, Confederate Sheila and Imperial Arrk Seth, have a similar origin - directly from spaceport rats. Sheila, born “on the other side of the law,” returns to the fold of the Confederacy, having lost all her loved ones. Not satisfied with only serving the Family of Humanity, she seeks destiny “on the side” - in Realized Probability, in the galactic empire of evil created by a certain Best-Seller Author from an unknown planet. Arrk Set, not seeing any other reality other than the imperial one, asserts himself in the only possible way, in his opinion - through galactic usurpation. Sheila appears in time to prevent a galactic war, save Arrk from death and reveal to him a different reality - her own. Enriched by the experience of the Confederation, Arrk returns to his home world to help save it from a new - external - threat. The task is not easy, but the relationship between the heroes is even more difficult.
