The Desvelado Book Club, courtesy once again of the Austin Public Library, has raced through "Mexico City: a cultural and literary companion" by Nick Caistor, which, though a bit repetitive in places, has the best nutshell political history of the Mexican Republic I've ever found, along with more about Posada the engraver than I've ever known before and some fine reminiscences of living in the Federal District before the population was so large.
