Ernest Hemingway's "A Farewell to Arms": While reading it I found it extremely boring, though there was this feel to it that still made it pleasant to read. I can't really describe it.
Plutarch's "Lives" from the main figures from the end of the Republic (Penguin Classics collection): By far the best books on Roman history I've ever read.
Livy's books on the Second Punic War (Penguin Classics collection): A bit extensive, very detailed. I liked Plutarch's better (even though he's a bit more imaginative according to modern historians), but nevertheless a great read.
Various books by Machado De Assis (Quincas Borba, Helena, among others): National author, I just love his books, even though they all share a common plot.
A book on Alexander the Great. Can't remember the author. It was a summary of his life and conquers, very short but entertaining reading.
This year I'm planning to read some more Ancient History narrated by the classics, some Shakespeare and maybe Nietzsche or Dante (heavy reading I guess). I'm just as fond of history as of fiction, as Livy puts it:
I shall find in antiquity a rewarding study, if only because, while I am absolved in it, I shall be able to turn my eyes from the troubles which for so long have tormented the modern world...
