But what he finds was nothing he was expecting, something he simply cannot comprehend.

Tyrone Leonard M.D., the leader of the research into the new subspecies takes Steven deep into the science of the new species. In short, Dr. Tyrone Leonard has found the next step in the human evolution, he has found Homo sapiens predaer, more commonly known as Homo sapiens predator.
