Description: From its birth on the slopes of Mount Paektu to its meeting with the sea, the Tumen River traces one of the most geopolitically charged borders on Earth. This sweeping account weaves together geology, ecology, and centuries of history to reveal how a single waterway has shaped—and been shaped by—the ambitions of China, Korea, and Russia. Along the way, it examines ancient kingdoms, colonial mapmakers, Cold War tensions, and the fragile ecosystems that persist between fortified banks. A thoughtful portrait of a river whose future remains as contested as its past.
