Lost in Time: Origin of Mankind

This audiobook is narrated by a digital voice.

After another passage through the Time Gate, Peter, originally from the 20th century, finds himself deep in the past, at the very dawn of humanity. Terrifying predators and a harsh landscape nearly bring him to his knees. He encounters two types of humans: the rough and bloodthirsty Neanderthals, and the not so different but somewhat friendlier early humans.

After initial, not so friendly contacts with the local people, he discovers that through solidarity and friendship, he can survive even in these conditions.

Amidst dangerous hunts and encounters with hostile warriors, he gradually learns about the existence of a mysterious civilization led by a mysterious bloodthirsty hybrid. It's only a matter of time before their paths cross.
