Roadside Picnic is considered one of the great examples of Soviet science fiction. First published in English in 1972, the book received new translation in 2012, along with a forward by Ursula K. LeGuin and an afterword by Boris Strugatsky about the struggles of getting the book through Soviet censorship controls. All three are a fascinating read.
The book has also resonated in the realm of pop culture, inspiring the Soviet film Stalker (1979) and the video game S.T.A.L.K.E.R. (2007). The story concerns a researcher paid to explore the site of an extraterrestrial visit and bring artifacts back to safe zones for study. However, he finds a growing temptation to return to illegally recovering the artifacts for sale on the black market as his life begins to spin out of control.
