'Assia was my true wife, and the best friend I ever had', wrote Ted Hughes, after his lover surrendered her life and that of their young daughter in 1969, six years after Sylvia Plath had suffered a similiar fate. Diva, she-devil, enchantress, muse, Lillith, Jezebel – Assia inspired many epithets during her life. The tragic story of Sylvia Plath and Ted Hughes has always been related from one of two points of view: hers or his. Missing for over four decades had been a third: that of Hughes's mistress. This first biography of Assia Wevill views afresh the Plath-Hughes relationship and at the same time, recounts the journey that shaped her life. Wevill's is a complex story, formed as it is by the pull of often contrary forces.
