Children's LiteratureEach of the seven chapters in this book highlights different events relating to cosmic rocks and colliding fireballs in the sky. The powerful impact that these phenomena will have on us is hard to calculate, but scientists do know that sometime in the future it is possible that we will discover a large space rock on a collision course with earth. Protecting our population will take top priority, but how can we do that? Some suggest that we should build a space robot that would land on the rock and change its speed and direction. Others feel that the best course of action would be to blow apart the rock with nuclear explosives. Predicting when and how this may happen is impossible, but with some luck we'll have a few million years to figure it out. 2001, Millbrook Press, $23.90. Ages 8 to 12. Reviewer: Sharon Tolle
School Library JournalGr 4-8-Bortz takes readers on a whirlwind tour of the origins of the universe, the impact of comets and asteroids on the history of the Earth and the Moon, what we have learned from current research about these space rocks, and what we might expect in the future. The full-color and black-and-white illustrations and photographs are sharp, clear, and dramatic. The layout creates interest while the crisp text makes for easy reading. The author brings to light a great deal of information about comets and asteroids and the people who study them and does so in an easy-to-understand and interesting style. The colorful cover is sure to attract students' attention, and even reluctant readers will be hooked after reading the first few pages. This title has plenty of science for basic research and may spark an interest in the study of Earth and its preservation. The only flaw is the lack of a clear definition of comets and asteroids. Otherwise, this title should have a deep impact on budding sky watchers.-Linda Wadleigh, Oconee County Middle School, Watkinsville, GA Copyright 2001 Cahners Business Information.
