Buck Rogers in the 25th Century/Planet Of The Apes Crossover by Paul Robison- Buck's quest for an ancient doomsday device leads to the discovery of a sector of Earth ruled by an entirely different species, with a centuries long hatred of man as a savage, primitive beast.  What future awaits the people of the Inner City as they ponder this difficult scenario while a revenge-filled Draco prepares to strike? What help can be provided by the 20th Century astronaut, Taylor? By the sympathetic apes, Cornelius and Zira? Can Earth survive, half-human and half-ape?
