About the book (from Wikipedia):
Waiting for Godot is a play by Samuel Beckett, in which two characters, Vladimir (Didi) and Estragon (Gogo), wait for the arrival of someone named Godot who never arrives, and while waiting they engage in a variety of discussions and encounter three other characters. Waiting for Godot is Beckett’s translation of his own original French play, En attendant Godot, and is subtitled (in English only) “a tragicomedy in two acts”. The original French text was composed between 9 October 1948 and 29 January 1949. In a poll conducted by the British Royal National Theatre in 1990 it was voted the “most significant English language play of the 20th century”.
