According to the flap on the back of the dust jacket, both author and illustrator are award-winners in their fields.  But picture books depend upon the story and the illustrations supporting each other and enhancing each other, but in this case they don’t.  The pictures really don’t seem to even fit the story.  The story’s not bad on its own.  It opens with a little girl describing her perfect pet to her parents (soft and cuddly and quick and strong, able to both fly and swim, able to shrink so small it can hide anywhere, and also to grow big enough to protect her).  After her parents tell her such a pet does not exist, she goes to bed and meets her perfect pet, and enjoys a whole night of adventures with it.  The illustrations, though kind of cool in their own right, don’t fit the story:  when the words say the creature is soft and cuddly, it looks rather sharp and geometric; when the words describe it’s sparkling eyes, the illustrations don’t support that, the wings that are described as broad and beautiful appear rather small and stubby.
