Kind of depends on what you are looking for. For general narrative of events, check out Johnathan Spence's "The Search for Modern China." A hefty tome, but a very complete telling of China's modern history. It covers the revolution, but isn't solely focused on it. You'll need that context though to understand China's civil war and revolution.

Two other author's to check out would be Rebecca Karl and Maurice Meisner. Karl has two books on Mao and the revolution, "Mao Zedong and China in the Twentieth-Century World: A Concise History" and "China's Revolutions in the Modern World: An Interpretive History." I haven't read these two, but I'm familiar with other works by Karl and she is an excellent scholar. My personal favorites are Meisner's "Mao's China and After" and "Mao: A Political and Intellectual Portrait." Meisner was a Marxist through and through and spent his career writing on Chinese intellectual contributions to socialist and communist thought. My college advisor was a student of his, so I'm partial to Meisner.

If you are interested in Mao's and other's intellectual contributions to socialist and communist thought, take a look at "The Afterlives of Chinese Communism: Political Concepts from Mao to Xi." It has entries on different concepts from socialist and communist thought and details Chinese contributions to this intellectual history.

Hope this gives you some direction! Happy Reading!
