What if the Civil War lasted for 15 years? What if the Underground Railroad was nothing more than a footnote in history? This is the world that Riq, Dak, and Sera must save us from as they travel back in time to 1850. As they fight to correct history, we also learn more about Riq and his own family stories, and why this mission is vital not just to the world as a whole, but to him personally. The third book in the Infinity Ring keeps the series going strong. A must read for historical fiction, as well as science fiction, fans. Recommended for grades 4-8.
