Papua. Gar Randolph, #1

Papua, with its vast regions of unexplored jungles and isolated indigenous tribes, is home to a medicinal plant with potent curative powers. The plant's unique ability to regenerate human nerves is even more consequential. Neurological scientist Ripon Siraj and his research botanist sister, Rava, search Papua's interior rivers for this rare miracle plant when they become the target of a scurrilous Asian virologist.
A co-worker and his girlfriend are mistaken for Rip and Rava and are murdered. Rip calls Washington D. C. for help. Gar Randolph and his unconventional Grey Hawk International team soon intervene to provide support and protection. Papua's jungles run deep with intrigue. The Taritatu River reveals breath-taking beauty around every bend but beware. Deadly inhabitants lurk in the shadows. Tension poisons serenity.
Everyone comes under a cloud of danger.
