In his eighties, Colin Thubron undertakes a dramatic and often dangerous journey from the secret source of the Amur to its giant estuary, covering nearly 3,000 miles.

The Amur River, originating from the mountains of Mongolia and flowing through Siberia to the Pacific, forms the tense border between Russia and China. This is the most densely fortified border in the world.

With setbacks from injuries and arrests by the local police, Thubron advances along the Russian and Chinese shores. By the time he reaches the desolate mouth of the river, a whole, crucial world has come to life.
