Fluva, the Drowning World, is a rain-drenched planet on the fringes of the Commonwealth whose indigenous species, the warlike Sakuntala, and its immigrant species, the hardworking Deyzara, stand on the brink of civil war. The wettest place on Fluva is Viisiiviisii, an immense jungle thriving with exotic plants and deadly predators. Endless rains have made the jungle a treasure trove of rare and valuable botanicals. A man can get rich there. Or die trying. Bio-prospector Shadrach Hasselemoga has come to seek his fortune—if he survives the terrain once his sabotaged ship goes down. When a Sakuntala and a Deyzara are dispatched to rescue the unfortunate soul, their ship crashes, too. Now, in order to survive, the three unlikely allies must do something that no one has ever done before: escape the Viisiiviisii before it consumes them. . . .
