If the Earth had a best friend, who would it be? Why, the Moon, of course! As in Earth! My First 4.54 Billion Years (2017), McAnulty gently introduces a celestial body by letting it tell its own story. The Moon excitedly explains how she came to be and her close relationship with the Earth. She also dispels some myths about herself: a cow has yet to jump over her, despite what nursery rhymes may say. Unafraid to insert specific numerics into the conversational text, this book imparts loads of scientific facts under the guise of a lighthearted autobiography, and the reader can't help absorbing much along the way. The humorous voice, accompanied by Lewis' adorable and entertaining digital illustrations, makes learning a breeze. Back matter includes a short author's note, a game of Two Truths and a Myth with Moon, as well as more data, nomenclature, and a list of sources. Perfect for children and grown-ups who have questions about the greater universe.--Emily Graham Copyright 2019 Booklist

In a companion to Sun! One in a Billion, an anthropomorphic Moon--rendered by Lewis as a friendly figure with doe eyes and a sweet smile--announces that it is BFF's with Earth (an equally affable figure who shows its appreciation for Moon with a tender half hug). "We have been together since the beginning. Almost," Moon begins. It describes how it came into existence (from a giant impact with "baby Earth"), explains the moon's phases, and details the way that gravity "pulling on Earth's oceans" causes the tides. Moon provides facts about itself and about various planets and their moons, while clearing up misconceptions and myths (it doesn't go away during the day, and cows don't jump over it). McAnulty conveys complex concepts in a gentle, clear manner that provides readers with a solid foundation for learning more about the galaxy. Ages 4--8. (June)
