This is a colorful and engaging way to introduce young children to the important role the sun plays in the Earth’s water cycle. Molly Bang teams up again with MIT professor, Penny Chisholm to complete The Sunlight Series, books that explore the sun’s role in the water cycle. Using expressive language, the narrator (the sun) tells the reader about the importance of her role in keeping a healthy balance to life, how she promises to do her part, and asks the reader if he will do his. Bang’s folk art illustrations, with the vibrant hues of blues, yellows and greens gives the story an earthy feel. Notes can be found in the back of the book with additional information.
