The Book of Disquiet is the Portuguese modernist master Fernando Pessoa's greatest literary achievement. An "autobiography" or "diary" containing exquisite melancholy observations, aphorisms, and ruminations, this classic work grapples with all the eternal questions. Now, for the first time the texts are presented chronologically, in a complete English edition by master translator Margaret Jull Costa. Most of the texts in The Book of Disquiet are written under the semi-heteronym Bernardo Soares, an assistant bookkeeper. This existential masterpiece was first published in Portuguese in 1982, forty-seven years after Pessoa's death. A monumental literary event, this exciting, new, complete edition spans Fernando Pessoa's entire writing life.
