Sylvia Plath (1932-1963) was one of the writers who defined the course of twentieth-century poetry. In the Letters, we discover the art of Plath's correspondence. Most has never before been published, and it is here presented unabridged, without revision, so that she speaks directly in her own words.The letters document Plath's extraordinary literary development: the genesis of many poems, short and long fiction, and journalism. Leading Plath scholars Peter K. Steinberg and Karen V. Kukil, editor of The Journals of Sylvia Plath 1950-1962, provide comprehensive footnotes and an extensive index informed by their meticulous research. Alongside a selection of photographs and Plath's own drawings, they masterfully contextualise what the pages disclose.This later correspondence witnesses Plath and Hughes becoming major, influential contemporary writers, as it happened. Experiences recorded include first books and other publications; teaching; committing to writing full-time; travels; making professional acquaintances; settling in England; starting a family; and buying a house. Throughout, Plath's voice is completely, uniquely her own.
