In the fifth Tarzan adventure, Tarzan returns to the lost city of Opar, a lost colony of Atlantis. Greedy bad guys follow Tarzan to Opar to rob the city of its stores of gold, and when Tarzan is hit in the head, he gets a bad case of amnesia, so he doesn't recall his wife and son, so when Jane is kidnapped, how is he going to remember her in time to save her? Plenty of action and intrigue, and a must-read for all Burroughs fans.
