Banished from her tribe, Skyra Una-Loto wanders through an ancient landscape teeming with fierce predators, searching for a way to overcome her crippling fear after witnessing a brutal tragedy. The problem is, to reclaim her strength she must attack and kill predators that will surely kill her first.
Skyra’s quest takes a surprising turn when she encounters a creature unlike anything she has seen before. It walks on four legs, yet it can fly. It eats fire instead of flesh, and it speaks a strange language called English. Its name is Ripple.
Having jumped 47,000 years into the past, the robotic drone Ripple completes its research mission and is stranded here forever. But now it has found a living, breathing Neanderthal to study. The more Ripple learns about Skyra, the more the drone is convinced she is important to the future of this world—but only if Ripple can keep her alive.
