Sylvia Plath (; October 27, 1932 - February 11, 1963) was an American poet, novelist, and short-story writer. Born in Boston, she studied at Smith College and Newnham College at the University of Cambridge before receiving acclaim as a poet and writer. She married fellow poet Ted Hughes in 1956, and they lived together in the United States and then in England. They had two children, Frieda and Nicholas, before separating in 1962.

In 1963, after The Bell Jar was published, Plath began working on another literary work titled Double Exposure. It was never published and disappeared around 1970. Theories about what happened to the unfinished manuscript are repeatedly brought up in the book Sylvia Plath's Fiction: A Critical Study by Luke Ferretter. Ferretter also claims that the rare books department at Smith College in Massachusetts has a secret copy of the work under seal. Ferretter believes that the draft of Double Exposure may have been destroyed, stolen, or even lost. He presumes in his book that the draft may lie unfound in a university archive.  The Colossus received largely positive UK reviews, highlighting Plath's voice as new and strong, individual and American in tone. Peter Dickinson at Punch called the collection "a real find" and "exhilarating to read", full of "clean, easy verse". Bernard Bergonzi at the Manchester Guardian said the book was an "outstanding technical accomplishment" with a "virtuoso quality". From the point of publication she became a presence on the poetry scene. The book went on to be published in America in 1962 to less glowing reviews. Whilst her craft was generally praised, her writing was viewed as more derivative of other poets.  It was Plath's publication of Ariel in 1965 that precipitated her rise to fame. As soon as it was published, critics began to see the collection as the charting of Plath's increasing desperation or death wish. Her dramatic death became her most famous aspect, and remains so. Time and Life both reviewed the slim volume of Ariel in the wake of her death. The critic at Time said: "Within a week of her death, intellectual London was hunched over copies of a strange and terrible poem she had written during her last sick slide toward suicide. 'Daddy' was its title; its subject was her morbid love-hatred of her father; its style was as brutal as a truncheon. What is more, 'Daddy' was merely the first jet of flame from a literary dragon who in the last months of her life breathed a burning river of bile across the literary landscape. [...] In her most ferocious poems, 'Daddy' and 'Lady Lazarus,' fear, hate, love, death and the poet's own identity become fused at black heat with the figure of her father, and through him, with the guilt of the German exterminators and the suffering of their Jewish victims. They are poems, as Robert Lowell says in his preface to Ariel, that 'play Russian roulette with six cartridges in the cylinder.'"  Some in the feminist movement saw Plath as speaking for their experience, as a "symbol of blighted female genius." Writer Honor Moore describes Ariel as marking the beginning of a movement, Plath suddenly visible as "a woman on paper", certain and audacious. Moore says: "When Sylvia Plath's Ariel was published in the United States in 1966, American women noticed. Not only women who ordinarily read poems, but housewives and mothers whose ambitions had awakened [...] Here was a woman, superbly trained in her craft, whose final poems uncompromisingly charted female rage, ambivalence, and grief, in a voice with which many women identified."  The United States Postal Service introduced a postage stamp featuring Plath in 2012.Answer this question using a quote from the following article:
