Drowning World
Alan Dean Foster
 On the distant planet Fluva, torrential rains that leave it barely habitable also make it a treasure trove of rare botanical specimens. When the human prospector Shadrach Hasselemoga crashes in a remote area, the only crew available to search for him is the warrior Jemunu-jah, one of the native Sakuntala, and the immigrant Deyzara trader, Masurathoo. This culturally different and physically repulsive to each other couple promptly crash also. While the rescuers and the rescued are all slogging it out of the ultimate rain forest, the reptilian AAnn empire is fomenting bloody trouble between the Sakuntula and the Deyzara. This leaves Commonwealth administrator Lauren Matthias in the hot seat, with refugees swarming in to her limited facilities and the bodies of the innocent piling up, with few resources to help. But it's the survivors of the rain forest who bring new knowledge that helps save Fluva, along with quick work by Matthias.
