Tough to get through, but the translation might not be as stellar as its ubiquity would lead one to believe. To be honest, the short biography of Pessoa in the introduction is the most interesting thing to me. His lifestory is fascinating, but the writing actually produced under his various heteronyms ranges significantly in quality as well as style. Book of Disquiet, his journal-like book under the name Bernardo Soares seems like it may be better.
