Publishers are reporting spikes in the sales of The Plague by Albert Camus, as summarized here in The Guardian. Apparently it is out of stock on Amazon! Uncanny.
The Plague is a fine read, however, I prefer Journal of the Plague Year by Daniel Defoe, available here via Project Gutenberg.
For those seeking a similar fictional experience yet more suitable to a shorter attention span, the film Contagion by Steven Soderbergh will suffice.
Enjoy.
