Marina Tsvetaeva, who returned to her homeland after 17 years of emigration, was not welcomed in the USSR with open arms. Rather the opposite. They prevented me from living, breathing, and not letting me print. And yet she became one of the most widely read and beloved poets of Russia. This phenomenon is explained not only by her talent. Ariadne Efron, the poet's daughter, made the return of her mother's creativity to her homeland the goal of her life. She gave Marina Tsvetaeva a second life - bright and triumphant. At the cost of what efforts it became possible, the reader will learn from the letters of Ariadna Sergeevna Efron (1912-1975) addressed to Anna Alexandrovna Sahakyants (1932-2002), the editor of the first Tsvetaev publications, and subsequently a leading researcher of the poet's life and work. The letters are interesting and talented. They tell about M. Tsvetaeva, her surroundings, her poems and prose, and of course, about time - literary and everyday events reflected in sketches of the life of a large country in a difficult, critical time.
