TARZAN, LORD OF THE JUNGLE When slave traders and safari hunters invade Tarzan's jungle kingdom, the mighty ape-man is caught up in a perilous quest for the lost Leopard City of Nimmr, a treasure land of amazing wealth. But Tarzan's cunning enemies vow his destruction, and the fabulous metropolis in the Forbidden Valley holds its own horrors of medieval mortal combat . . .
TARZAN AND THE LOST EMPIRE While searching for a missing scholar in the treacherous Wiramwazi Mountains, Tarzan is captured by an ancient tribe of the centuries-dead Roman Empire. In this dangerous throwback to Caesar's brutal regime, Tarzan must triumph over cruel emperors, skilled gladiators, and blood-hungry lions--or he will never taste freedom again . . .
Edgar Rice Burroughs was an American author, best known for his creation of the jungle hero Tarzan and the heroic John Carter, although he produced works in many genres.
Overall, these are the two best books so far. Both stories flowed better, alas Burroughs CANNOT sum up a story to leave you satisfied. Both books are similar in format, two communities separated from home for hundreds and thousands of years, living in a past system in a modern world. They both have had no contact with their own countries and seem happy with that.
Tarzan swoops in, the story flows nicely, then it stops.
