One of these additional continents, Atlantis, was located in the Atlantic Ocean between North America and Africa. The other, Lemuria, was located in the Pacific Ocean. In this book, you’ll learn all about these huge continents and the great civilizations who called them home. What did they look like? What was daily life like for them? What happened to them? Tom asks these intriguing questions and many more. The answers revealed on the pages within dig into the mysteries surrounding the continents of Atlantis and Lemuria and their eventual destructions.
