The Neanderthals (Nea) became extinct about 30,000 years ago, about 10,000 years after Early Modern Humans (Sap) reached Southern Europe. This book is historical fiction concerning the extinction of the Nea. The early chapters are about the culture and social organization of the Nea and the Sap. Later chapters describe armed conflict between the Brown Bear tribe of the Nea and the Sap invaders. The Brown Bears learned their fighting skills from the Nea groups who invaded their land, which prepared them to fight the Sap when they came. Eventually, a group of Sap came onto Brown Bear land, and started to build a camp; the Bear fighters prepared to challenge them. The battles began, and these are described in the final chapters of the book.
