Xavras Wyżryn [ˈksävräs ˈvɨ̞ʐrɨ̞̃n] is an alternate history novel by the Polish science fiction writer Jacek Dukaj, published in 1997.

An alternate history novels, it discusses Polish martyrology, circling on the philosophical aspects of war, shows the thin line between terrorism and freedom fighters.

The actual story takes place in the 1990s and is told from the point of view of an American reporter, who is an embedded journalist with the anti-Soviet Polish resistance.

Smith does not realize that during his long trip from Ukrainian steppes to Moscow along with hardened veterans of Polish forces, he will experience the horror of war in which there is no good and evil side.

He also expect to find himself in the midst of the most reckless of Wyżryn's campaigns in which the Polish forces capture a Soviet atomic bomb and start to smuggle it towards Moscow.

The war took place mostly on the former Polish and Ukrainian territories and lasted until 1944, when Allied forces dropped three atomic bombs on Leningrad, Kyiv and Warsaw to stop the Soviet armies.

People living inside the "Atomic Triangle" became hardened nearly soulless creatures, balanced on the edge of death and became numb because of the great suffering of the whole nation.

The whole Central-Eastern Europe was now known the European War Zone (EWZ), and reached as far as Constantinople in the south, Finland in the north, the border with Prussia in the west and the Dnieper River in the east.

The US government secretly finances the guerrillas, and Western Europe fortifies its borders to defend against presumed Soviet or a Chinese attack, the latter of which is more feared.

Other threads of the work that received literary commentaries concern, among others, national and religious symbolism, the morality of terrorism and the role of the media in shaping public opinion.

As in the Chechen conflict, neither side holds a moral high ground since both commit horrible war crimes to reach their goals.
