This is from a review of new books, contributed to the October HARPER'S Magazine by Joshua Cohen.
"Fiction is one of two ways we currently have of traveling through time. The other is to travel from South to North Korea: from Samsung-sponsored clamor to a dictatorship of barbed-wire penal camps with nary a bar of WiFi. It's nearly as difficult for an American to obtain a visa to the SPRK as it is to obtain copies of the hundred books its government has approved for reading."
That's a nice passage, and allows Cohen a segue between the sci-fi novels he had just been talking about, into a Korean-American publishing project, Dalkey's Library of Korean Literature.
