This book is about a cat who wonders to whom the moon belongs, and various animals and natural resources respond -- the trees, bird, ocean, wolves... and the moon responds. The cat sleeps, and when it wakes up, it wonders, to whom the sun belongs. Lovely use of line and color in these illustrations which capture your attention.
I wish that all picture books included notes about the artistic technique. I think this is watercolors and ink or pencil. Whatever it is -- the result is lovely.
Only one thing bothers me, and I'm not even sure about it, but it appears to me that the lining paper illustrations that go through the phases of the moon are progressing in the wrong direction, with the white appearing to grow from the left instead of from the right as the moon waxes towards the full moon. If I am looking at it right (the dark is not shown as solid, but with dots of increasing density, so it is a little unclear), the progression is opposite that. So I had to reluctantly change my rating from 5 to 4. Most people will probably not even notice, but if you are reading this book in conjunction with many stories about the Moon, the Solar System, or Space, as I would do, I would either point this out or be extra cautious not to show the lining papers, as it would counteract the effort I do in using Oreo cookies or other ways to have children learn phases of the moon so they can look at the sky and figure for themselves, is the moon moving towards Full moon or waning towards another New Moon. It could be easily remedied in future printings if the author/illustrator takes note.
