Roadside Picnic was probably the first Russian novel I ever read.
Written by brothers Boris and Arkady Strugatsky, it tells of the post-visitation of alien beings - aliens who stayed only a short time, were not seen, did not communicate with us, or showed any recognition of our existence. The sites of the visitation are littered with dangerous anomalies and artifacts - many of which hold amazing powers and are highly sought after.
These artifacts, while valuable to humans, are theorised as being no more than discarded rubbish left after a 'roadside picnic'.
Arkady passed away many years ago, but Boris (born 1933) has just died of heart problems and pneumonia. A computer scientist and astronomer until he became a fulltime writer in the 60s, he was a major writer, not only in Russia but worldwide.
R.I.P. Boris.
