Vou dar uma olhada nos romances de Horseclans de Robert Adams
The books mainly concern the doings of the "Horseclans", a nomadic people originating from the "Sea of Grass" —the Great Plains from present-day southern Canada to central Texas, and from the Mississippi River to the Rocky Mountains, post-apocalyptically. The Horseclansmen were portrayed as fierce, noble and often gifted with telepathy, which came in handy for their dealings with their horses and "cats"—sabertoothed tigers that had been revived by scientific means in the years before the nuclear war.
