Milestones (Vyorsty) is an early collection by Marina Tsvetaeva (1892-1941), published in Moscow in 1922, before she left the country for the West. The book celebrates–among other things-her friendship with fellow-poet, Osip Mandelstam, and was her most innovative collection to that point, as well as an indication of the way her work would develop in her full maturity as a writer.
