In the second book of this new environmental series from the sustainability specialist and Greek State Award-winning author, that draws upon the teachings of the Tao, the two siblings must solve a complex riddle about a sad panda, while an ancient Chinese myth takes them on unexpected adventures around the city of Athens. The Dao Warriors won’t give up: the planet’s animals are in danger and only Tu and Di can save them!
