Venture deep underwater in search of the lost city of Atlantis and an incredible treasure!

Start on the shore and progress through various marine ecosystems. Along the way you will encounter aquatic flora and fauna, face a fearsome sea monster, and find a long-lost treasure

Children will choose one of three submarines to pilot, each with different specialties. As they play through the adventure, they will collect new technologies to upgrade their submarines. But beware! Too many poor decisions will lead to the accumulation of leaks and returning to shore.

There are multiple endings with different levels of success. Through the process of making choices and learning from outcomes, children will grow in experience and be encouraged to use critical-thinking and deduction to overcome challenges

Selecting different characters, or choosing different paths, means that they will return to this book for a new adventure, time and time again!
