Set in a vividly reimagined Cretaceous period, this classic fantasy-prehistory novel follows a tribe of early humans navigating a world teeming with giant reptiles and primeval landscapes. Along the shores of a vast inland sea that will one day become Colorado, the tribe battles towering lizards, massive toothed birds, and other fearsome creatures for survival.

Blending adventure with a rich, atmospheric portrayal of a steamy, tropical Earth, the story transports readers to a time when monstrous dinosaurs and primitive humans might have coexisted, amid strange forests and ancient seas.
