'The world is blood-hot and personal': in her moving and illuminating introduction, the poet Emily Berry remembers her own teenage encounters with Ariel and offers a personal way into this definitive collection. She shows us how Plath can crystallize our most volatile emotions, transforming them into images so potent and precise that they resonate with us all. Plath has been an inspiration to successive generations; her influence, enduring and profound.'If the poems are despairing, vengeful and destructive, they are at the same time tender, open to things, and also unusually clever, sardonic, hardminded . . . They are works of great artistic purity and, despite all the nihilism, great generosity . . . the book is a major literary event.' A. Alvarez, Observer, 1965
