RIDING ON THE WINGS OF A DRAGONFLYThe Dragonfly Race is set to begin in Piffle World, and the prize for one lucky lightweight aircraft pilot is an amazingly powerful battery in the shape of a feather. But for the four dimension-travelers, and one odd creature named Mokona, who have joined the competition, the feather represents more than energyâ€“itâ€™s one of Princess Sakuraâ€™s lost memories! And Sakuraâ€™s feather isnâ€™t the only ting at stake. Despite President Tomoyoâ€™s best efforts to protect the race using her wealth and resources, unexpected hazards keep popping up, and the perilous contest could lead to death for unskilled pilots . . . like the princess!
