This book is addresses, with just wot exceptions, to Sylvia Plath, the american poet to whom he was married. They were written over a period of more than twenty-five years, the first a few years after her suicidie in 1963. Intimate and candid in manner, they are largely concerned with the psychological drama that led both to the writing of her greatest poems and to her death. Countless books have discussed the subject form a necessary distance, but this is the first time that Hughes has given his personal account.
