The illustrations and simple text were the first things that attracted me to this book. It starts out with a view from space and the words, “The world is full of great big things:”. It goes on to show really big things: a canyon, billions of stars, the wide desert. And then it focuses on one mouse who travels throughout the book in the wind, on a massive train, through a forest, with only a crumb and at the end reaches another mouse and gives them the crumb. The message is that great big things are very small when you go through them for someone you love.
