What an honor! Here is the their description of the book:
The water cycle is a topic children are exposed to daily – and it’s as mysterious as it is ubiquitous, making this book equally accessible and exciting. Miranda Paul seizes on this fact, using simple poetic language that allows young readers to flow through the book in the same way water transitions forms seamlessly page to page. Children will connect with Jason Chin’s beautiful illustrations of familiar environments, which expertly tie into and add depth to the text. Paul’s back matter elaborates on her water cycle narrative, providing facts, infographics, and calls -to -action for her readers, who will no doubt be drawn to Water is Water for both its information and beauty.
