Probing the depths of the modern psyche in a voice at once caustic and vulnerable, melancholic and humorous, Baudelaire's infamous book brings to the surface a new understanding of evil, of eroticism, and of social life through an astonishing variety of poetic forms and styles. This edition adds the poems banned from the original 1857 publication to the expanded collection of 1861 and includes an introduction from the translator, acclaimed poetry scholar Nathan Brown.
