Fifty new books, celebrating the pioneering spirit of the Penguin Modern Classics series, from inspiring essays to groundbreaking fiction and poetry. ‘But no, she’s abstract, is a bird, Of sound in the air of air soaring, And her soul sings unencumbered, Because the song’s what makes her sing.’ Dramatic, lyrical and ranging over four distinct personae, these poems by one of Portugal’s greatest poets trace a mind shaken by intense suffering and a tireless search for meaning.
