Written at the height of the Cold War, and it shows. There is an abundance of memoirs by individuals who observed or participated in the events of 1917-1924 which make for much better, and easier, reading. Lunacharsky's "Revolutionary Silhouettes" is delightful. "Lenin" by Landau-Aldanov is opinionated and entertaining. Others include "Days with Lenin" by Maxim Gorky; "Russia in the Shadows" by HG Wells; "Encounters with Lenin" by Valentinov; and many more. If one is looking for a serious analysis of Lenin's political thought, modern writers such as Neil Harding and Lars Lih are more useful.
