Anna Sahakyants' new book talks about the personality and fate of the poet. This work is not a biography of M. Tsvetaeva in its pure form, nor is it a literary monograph, although it includes both. Unique previously unpublished materials, a significant part of which the author received from Tsvetaeva’s daughter, Ariadna Efron, allow us to make new discoveries in the work of the great Russian poet. The book is an appendix to the seven-volume collected works of M. Tsvetaeva.
