In the prime of her life, the intrepid aviatrix, Gloria James Jessup, crash-lands in the wild jungle, leaving behind a wrecked aeroplane and her personal diary. Nearly two decades later, Tarzan finds out that an innocent man faces conviction for the aviator's death, and, secretly, follows the hidden path to the wondrous and fragile Blue Valley--the land of the magical fountain of youth--intent on bringing Gloria back to testify. However, is she the same person she used to be? And, above all, can Tarzan protect the vale's ultimate mystery from the unscrupulous opportunists who would like to exploit it?
