From the time fourteen-year-old Jane Ann Good crawls into a life boat aboard a doomed ship until she fulfills her promise to help a tribe of pygmies from deep in the Congo basin, she proves to be a force of strength and courage way beyond her young age. Fully mature, beautiful, and blessed with a gorgeous body as the result of precocious puberty, Jane also possesses an intellect far superior to those around her. She quickly earns the nickname, Jungle Jane, as she arrives in the French Congo after a long trek through the jungle with five pygmies seeking help with a smallpox outbreak in their village.
