Ken Ward and his brother, Hal, are headed south of the border, into the steaming jungles of Mexico. Hal's job is together specimens for a museum; Ken's is to keep Hal out of trouble--and prove himself as a jungle explorer.

Then an unexpected challenge beckons--the boys have the chance to be the first to run the rapids of the Santa Rosa, an unexplored river complete with army ants, giant snakes, wild pigs, and man-eating crocodiles! If they make it through, Ken will win a trip to Africa. If they don't...

Ken Ward in the Jungle is a wild ride from the immortal pen for America's greatest storyteller of outdoor adventure.
