Far From Home

Once the world lived in peace. People had families, friends, life was good. But that was a long time ago.
Since then there has been a few wars, nothing that lasted longer than 5 years. That was until there was the war that destroyed everything. Many...Most...All, died in that war. Almost all. There was no going back.
America wonders what was once called Earth. There used to be beautiful cities, like New York, London, Moscow, Tokyo, and many more. Those have since been destroyed. Anything that survived the war has been overgrown.
He travels with his trusty white German Shepard Eyota. The other survivors usually only keep dogs to detect radioactive areas that need to be avoided, or as a help while hunting. America, on the other hand, just keeps her because she is his best and only friend.
As he wonders he meets other survivors, makes enemies, friends, and may even meet someone special.
