This book reconstructs Marx and Engels's theory of freedom, highlights its centrality to their vision of the communist society of the future, traces its development in the history of Marxist thought (including Marxism-Leninism), and explains how it was transformed into a legitimation of totalitarian practices.
A dense and old-fashioned treatment of the subject matter, good for those who want a particular, in-depth perspective and are familiar enough with the topic they don't get bogged down with name dropping.
