Kite Day: A Bear and Mole Story by Will Hillenbrand is a great kite book!
The illustrations were created in mixed media. Hillenbrand's style is rich and uses deep colors. Check out his website. You can watch a video on how he creates, print off a page to go with one of his books, and more.
I used this in my Preschool Storytime, at my library branch and used it to take to daycares for stories. The little twist at the end, after the kite gets grabbed up by a storm, is serendipitous. We discussed, in storytime, how the bad luck for bear and mole loosing their kite turned into good luck for the birds. It's also a great story to help children think what might happen next. Will bear and mole get the kite back? Will they make a new one? Read it and decide what you think might happen next.
