Moctu and the Mammoth People is a compelling, well-researched story of a strong, young, dark-skinned Cro-Magnon boy who must fight his rival for leadership of his tribe and the right to mate the beautiful Nuri.

Besides having dangerous encounters with mammoths, wolves, and saber-toothed tigers, Moctu has to deal with his older rival, Jabil, who fights and undermines him at every opportunity. After Jabil murders several elders who go against him, he deftly shifts blame onto the Pale Ones. He takes over as the tribe's leader and makes Moctu's life miserable.

On a hunting trip, Moctu is captured and enslaved by the Pale Ones. While with them, Moctu is shocked to discover that, although these primitive people know little about spear-throwers or making clothes, they can make fire, and he learns the skill. He meets the blonde and fair-skinned Effie, and over time, he recognizes that his hate for the Pale Ones was misplaced. Realizing that Nuri by now has been mated to Jabil, Moctu falls in love with Effie and has a child. But when he uncovers evidence that Jabil murdered his tribesmen, Moctu knows he must return home and mount a challenge. When Moctu returns, can he overcome Jabil? How will Nuri react? The interspecies conflict may also get Moctu or Effie killed.
