The Book of Dalin (en Inglés) - James L. Steele

It is the last age of the dinosaurs.

The leafeaters have fought back against the carnivores and now live in cities, safe from danger, leaving the hunters to prey on one another.

The wilderness is an empty, violent place. The only life a predator has is to survive long enough to bring hatchlings into an existence of mindlessly walking from kill to kill, remaining one step ahead of starvation.

One hunter, Dalin, is determined to get out. Raised in a leafeater city as a symbol of how herbivores no longer fear predators, he made a mistake six years ago which exiled him to the wild, and he has barely held on to his conscious mind since.

He has one chance to return to civilization. Appealing to the leafeaters is even more dangerous than facing starving predators, but he is desperate enough to try.

Is giving up his freedom worth a full belly and the privilege to play his flute without fear? Will the herbivores accept a tamed hunter who has tasted life in the wild? Dalin may be the only hunter to learn speech, but can he convince the leafeaters that he is not like the others?

Perhaps there a greater reason he is the only predator to be conscious of his own misery.
