Gr 1-3 While exploring the hillside behind her new house, Julie finds a sparkly clear rock that her dad identifies as a crystal. He knows that it is made of quartz, that it comes from a vein in the ground, and that all crystals grow and have the same shape even if they are different sizes. While Julie is unfamiliar with technical terms such as "silicon dioxide" and "veins," she is fascinated by what her dad teaches her. The book successfully incorporates nitty-gritty detail about crystals. Soft pastel illustrations make this a warm, accessible introduction to rock collecting. The interplay between Julie and her dad and the infectious enthusiasm passed between the two add to the appeal of digging up treasure in one's own backyard. A four-page reproducible section "For Creative Minds" features tips on becoming a rockhound, a Moh's Hardness Scale for comparing minerals, and recipes that serve as models for understanding how different types of rocks are made. This book will find a place in either picture-book or natural-science collections.-Kara Schaff Dean, Walpole Public Library, MA
