The Book of Disquiet by Fernando Pessoa
The Book Of Disquietude or The Book of Disquiet (Livro do Desassossego in Portuguese), published posthumously, is one of the greatest works by Fernando Pessoa. It is signed under the semi-heteronym Bernando Soares. It is a fragmentary book, always being studied by the pessoan critics, and these have several different interpretations about the way the book should be organized.
