Nominated for Best Novel in 1989
In the year 6303, when earth is bare of anything larger than an insect or a mouse and most people have left for the stars, Duncan Rojas receives a most unusual visitor. His name is Bukoba Mandaka, and he is the last of the Maasai.
Mandaka wants Rojas, senior researcher for Braxton’s Records of Big Game, to find the tusks of the Kilimanjaro Elephant, tusks that weigh over 200 lb. each. Why? Mandaka will not say, but he will pay enormous sums for them. And Rojas cannot resist the challenge of tracing something lost for 3000 years.
Back and forth through time, in card games, wars, and rivalries, Rojas searches. But as he begins to glimpse the elusive, lost power of ancient Africa, he is seduced, and before long the quest has become his own.
