Book excerpt: One Day a Dot explores the age-old question: Where did we come from? Where did everything come from? Starting with one tiny dot and continuing through the Big Bang to the rise of human societies, the story of our universe is told in simple and vivid terms. But the biggest question of all cannot be answered: Where did that one dot come from? One Day a Dot is a beautiful and vibrant picture book that uses the visual motif of circles as to guide young readers through the stages of life on Earth.
