The Xishuangbanna Reserve in southern Yunnan is a land of giants. In the steamy jungles, Marven comes face-to-face with China's largest lizard, the world's biggest species of moth, a super-sized serpent, and a massive bamboo rat. But will he manage to track down the biggest giant of all, one of China's last remaining Asian elephants?

Marven explores the vast grasslands of Inner Mongolia. These rolling plains – once home to Genghis Khan and his army of horse warriors – are now inhabited by the elegant demoiselle crane, an ancient tribe that has a close relationship with a surprising animal, and speedy lizards and venomous snakes.
