“This is a story about the interaction of science and religion, told from the perspective of a 10-year-old,” writes reviewer David C. Kopaska-Merkel. “Nevertheless, there is a lot of science in this book, both fact and theory”—particularly concerning trilobites. While the book is aimed at a young adult audience, “I enjoyed reading it myself. The characters are solid and the story well told. The plot has enough twists and turns to satisfy.” Kopaska-Merkel concluded, “The book is as entertaining and thoughtful as any attempt I have seen to tackle the idea that religion and science are compatible. And not just liberal religion and science, but any religion and science.”
