Dance of the Tiger is a novel by Finnish paleontologist Björn Kurtén, published in 1978 and English translation in 1980. It is a prehistoric novel dealing with the interaction between Neanderthals and Cro-Magnons. A sequel, Singletusk, published in 1982, continues the story of the family.
Set 35,000 years ago in Scandinavia, during a thaw in the great Ice Age, the novel follows a Cro-Magnon named Tiger as he tries to defeat Shelk, a tyrant and a hybrid (Neanderthal/Cro-Magnon), the man who killed his father. With his family and much of his tribe dead, Tiger meets, interacts, and allies himself with groups of Neanderthals. He eventually marries a Neanderthal woman. [Source]
