Anton is an undercover operative from future Earth, who travels to an alien world whose culture has not progressed beyond the Middle Ages. Although in possession of far more advanced knowledge than the society around him, he is forbidden to interfere with the natural progress of history. His place is to observe rather than interfere — but can he remain aloof in the face of so much cruelty and injustice...?

Don Rumata has been sent from Earth to the medieval kingdom of Arkanar with instructions to observe and to save what he can. Masquerading as an arrogant nobleman, a dueler, and a brawler, he is never defeated, but yet he can never kill. With his doubt and compassion, and his deep love for a local girl named Kira, Rumata wants to save the kingdom from the machinations of Don Reba, the first minister to the king. But given his orders, what role can he play? This long overdue translation will reintroduce one of the most profound Soviet-era novels to an eager audience.

Red Schuhart is a stalker, a young rebel who is compelled, despite extreme danger, to venture illegally into the Zone to collect mysterious alien artifacts. His life is dominated by the place and the thriving black market in alien products. But when he and his friend Kirill go into the Zone together, something goes terribly wrong. The news Red receives from his girlfriend upon his return makes it inevitable that he'll keep going back to the Zone, again and again, until he finds the answer to all his problems. Back in print after 30 years, this brand new translation of a science-fiction classic has been supplemented with a foreword by Ursula K. Le Guin and a new afterword by Boris Strugatsky that explains the strange history of its original publication in Russia.
