Penner explores the mysterious legends of the unicorn from around the world in this beginning chapter book in the Stepping Stones series that follows the same format the author used for her previous exploration of dragon legends. The attractive cover shows a white unicorn silhouetted against a turquoise sky, with a circular logo clearly stating the work is fantasy. However, the boundaries of fact and legend are not so clear within the text. Short excerpts from legends are set in italics, but other unicorn myths are presented within the text as retellings of actual events or practices, blurring the line between the mythical and the historical. The final chapter details ways that people have attempted to create fake unicorns from other animals such as goats and bulls. Grant’s full-color illustrations of unicorns with flowing manes and tails will appeal to young horse lovers and unicorn devotees. (Nonfiction. 6-9)
