The Unbearable Lightness of Being is a 1984 novel by Milan Kundera about two women, two men, a dog, and their lives in the 1968 Prague Spring period of Czechoslovak history. Though written in 1982, the novel was not published until two years later, in a French translation (as L'insoutenable légèreté de l'être). The same year, it was translated from Czech into English by Michael Henry Heim, and excerpts were published in The New Yorker. The original Czech-language text was published the following year. A feature-length film adaptation of the same title was released in 1988. (Wikipedia, CC BY-SA 4.0)
