Martín Fierro. It is a (very long) epic poem about the life and times of one gaucho in rural and frontier Argentina. Beautifully written, with exquisite attention to rhyme, perfect use of local expressions, it also doesn’t pass upon oportunities to make social commentaries on the life and times of the characters.

The only downside is that you have to know Spanish in order to fully appreciate it. There are several very good translations that are faithful to the tone and the intention of the author, but the rhymes are invariably lost.

If it helps you feel a little better:

The book was a commercial success, but critics expressed doubts about the accuracy and validity of claims Perkins made in the book. Perkins was referred to as a conspiracy theorist by one reviewer, while a number of former colleagues at Chas T. Main disputed or disagreed with some of his allegations. Several reviewers discussed a lack of documentation or verification for Perkins’ claims.

The Prince, by Macchiavelli. Fantastic read, and it is written in a very easygoing style. It can be read in less than an afternoon.
