From the back of the book.
On your first solo journey to find the Lost Continent of Atlantis, you fail to bring back proof of your success. Now you and your colleague Horton James III are returning to document this amazing otherworld. But back below the surface of the sea dangers abound. A treacherous king lures you to riches, rebel slaves lure you to help lead a revolt; and the evil Nodoors aim to capture you and keep you below... for good. A greedy king, evil politicians, peace loving peoples- they are all residents in the underwater world of Atlantis. Do you want to stay below to help the Atlanteans? Or do you return to the surface with proof of the lost continents existence? Will you be taken prisoner before you even get to make that choice?
