These are not 1000 page books (but combined they can be):

- God's Chinese Son: The Taiping Heavenly Kingdom of Hong Xiuquan (more about the Taiping and their leader)

- Autumn in the Heavenly Kingdom: China, the West, and the Epic Story of the Taiping Civil War (more about the west's actions)

I just saw this book on Amazon and haven't read so might be a good read to round out the history: Struggle for Empire: The Battles of General Zuo Zongtang (Qing statesman and army officer, General Tso's chicken was named after him!)

Overall, I would say good English material on this conflict is a bit thin. I would recommend reading more about the Qing dynasty, Opium wars, first Sino Japanese war, Boxer Rebellion, Xinhai Revolution. /r/askhistorians always have good books recommendation.
