From the renowned creator of Tarzan and John Carter of Mars comes a tale of adventure among the shattered ruins of European civilization!

In A.D. 2137, Jefferson Turck, commander of the aero-submarine Coldwater, accidentally crosses the forbidden 30th meridian - becoming the first American in over 200 years to set foot on European soil - where he is plunged into a wild adventure among the ruins of once-great cities and their now-savage inhabitants.
