Book 7 highlights the vast, orderly nature of God's creation and emphasizes that children can cultivate good habits for future success.

Phyllis Duke, the author, holds a master's degree in educational supervision with a concentration on Early Childhood Learning. Her expertise encompasses the development of phonetic sounds, early phonics, linguistics, and conversational lines of thought and interest. Duke has created early reading books for children aged three through ten.

These books introduce challenging concepts, moral values, vocabulary recognition, and promote thoughtful life-changing attitudes and experiences. Additionally, the stories are designed to captivate children, subconsciously assisting them to believe they can read independently. This repeated engagement fosters self-confidence in their reading ability, encouraging them to explore literature that interests them. This approach instills a sense of confidence often lacking in other early reading materials and techniques.

Furthermore, the narrative skillfully intertwines themes of power, loyalty, betrayal, and redemption, creating a rich tapestry of human experiences. Each book builds upon the previous concepts, offering deeper insights into the characters' motivations and the consequences of their choices.

How Big is Our World? Book 7 introduces the vastness of God's creation, which is orderly. It also introduces the concept that each child can develop good habits which can guarantee success in their future.
