At the dawn of humanity, one tribe of cave people survives the many trials of prehistoric life under the wise leadership of Jemilla, the Peacemaker. Jemilla taught her people to express themselves rather than bash each other's heads with rocks or eat each other's babies. But one member of the tribe doesn't seem to fit in: Zazzalil. When she stumbles upon the most important discovery in history, she sets in motion events that will pit her tribe against woolly mammoths and saber-toothed tigers - and change the world forever. She'll travel from omega to alpha and become ... the Firebringer!
