John Carter has returned to Mars from Earth, he knows nothing of what has happened in the past 5 years. He appears on Mars in a land from which no one returns. However since he is ‘John Carter’, he does the impossible, only to find that his wife survived, but has disappeared.
The rest of the book is spent in his efforts to find her and his enemies efforts to stop him.
It is a very simple plot line and the action comes from the fact that every time John Carter gets close to success something happens to thwart his efforts.
Another quick enjoyable read. Lots of fighting again.
