When Jade Emperor drops two precious gems from heaven, he is devastated and his sorrow cloaks the whole world in darkness. To get them back, his children must journey to earth, traverse mountains and rivers, dive to the depths of the East Sea, and petition the Dragon Kings. With such a long and dangerous quest ahead, will they be able to restore the gems, and bring light back into the world?

Following the success of Poonam Mistry's How the Stars Came to Be, this next instalment in the How it Came to Be series is inspired by Vietnamese folk tales, and brilliantly brought to life by Saigon-based illustrator Wiliam Luong.
