"Tarzan and the Jewels of Opar" by Edgar Rice Burroughs is a novel first published in 1916. Tarzan returns to the lost city of Opar to recover gold from its hidden treasure stockpile after suffering financial losses. But danger follows—a treacherous Belgian officer tracks him, an earthquake leaves him without memory, and the beautiful high priestess La seeks vengeance after he rejects her love again. Meanwhile, Jane has been kidnapped, and an amnesiac Tarzan must navigate intrigue and betrayal while unknowingly carrying Opar's sacred sacrificial knife.
