How can he lead his people to survive when they are out of ammunition and food and have a powerful enemy on their side? What is that mysterious blue crystal? Is all this a conspiracy or an accident? See how he uses the modern knowledge in his mind to create the strongest prehistoric tribe. This novel and its characters are purely fictitious.
