I agree with John Jung and also enjoyed Sinn's Book
copied from John Jung site:
John Jung's insight: "Perhaps the most fascinating and enlightening book I've run across in recent years about Chinese immigration to North America. Scholarly, but highly readable, this masterpiece by Hong Kong scholar Elizabeth Sinn examines the significant impact of the transport of immigrants back and forth on ships between China and North America (similar arguments are likely to be applicable to Chinese who went to other places like Australia and New Zealand). We know from much research what happened to Chinese once they crossed the Pacific to reach North America, but the details of the operations of the ships that transported them are generally taken for granted or never mentioned, as if this process was unimportant. Sinn's book, in contrast, fills this void admirably and helps provide a filler contextual background of what immigration entails beyond answering the questions of immigration authorities. Sinn coins the term, in-between places, to describe the transitory and fluctuating domiciles of many immigrants who were neither here nor there for long periods. She not only details the economic and trade profits of shipping human cargo to and from China, but also material goods including opium, flour, and Chinese food and spices. She provides rich details of the traffic in prostitutes and slave girls as well as the transport of bones of Chinese who died overseas"
