Dring-dring! With the distinctive sound of their bicycle bells, Chirri and Chirra are off on another whimsical adventure. In this new installment of the beloved series, the twins brave a rainy day together...after all, stormy weather is no match for their boundless energy and curiosity. The pair happens upon a cafe that is only open on rainy days, and they sip tea with a side of sweet rock candy as they watch the droplets fall. They continue their journey, only to discover that the rain is now falling upside-down, their bicycles suspended on the droplets as they ride along. For these winsome twins, the world is a haven of endless discovery, of wonderful oddities, of adventure and excitement without danger. Kaya Doi's illustrations, rendered in glowing colored pencil, are warm and inviting for readers, ushering them into the pages like a safe haven from the rain outside.
