Professor Amelia Harsh is obsessed with finding the lost civilization of Camlantis, a legendary city from pre-history that is said to have conquered hunger, war, and disease with the creation of the perfect pacifist society. Without official funding, Amelia is forced to accept an offer of patronage from Abraham Quest, the man she blames for her father's bankruptcy and suicide. She hates him, but he has something that Amelia desperately wants—evidence that proves that Camlantis existed and that the Camlantean ruins are buried under one of the sea-like lakes that dot the murderous jungles of Liongeli. Amelia will blackmail her old friend Commodore Black into ferrying her along a huge river on his ancient U-boat.
