"On a mountain above the clouds, in the central highlands of Malaya lived the man who had been the gardener of the Emperor of Japan.”

Teoh Yun Ling was seventeen years old when she first heard about him, but a war would come, and a decade would pass before she travels up to the Garden of Evening Mists to see him, in 1951. A survivor of a brutal Japanese camp, she has spent the last few years helping to prosecute Japanese war criminals. Despite her hatred of the Japanese, she asks the gardener, Nakamura Aritomo, to create a memorial garden for her sister who died in the camp. He refuses, but agrees to accept Yun Ling as his apprentice ‘until the monsoon’ so she can design a garden herself.

Staying at the home of Magnus Pretorius, the owner of Majuba Tea Estate and a veteran of the Boer War, Yun Ling begins working in the Garden of Evening Mists. But outside in the surrounding jungles another war is raging. The Malayan Emergency is entering its darkest days, the communist-terrorists murdering planters and miners and their families, seeking to take over the country by any means, while the Malayan nationalists are fighting for independence from centuries of British colonial rule.

But who is Nakamura Aritomo, and how did he come to be exiled from his homeland? And is the true reason how Yun Ling survived the Japanese camp connected to Aritomo and the Garden of Evening Mists?
