A Boy and his Dog at the End of the World

The World Has Ended. At Least We Still Have Dogs.
My name's Griz.
I've never been to school, I've never had friends, in my whole life I've not met enough people to play a game of football. My parents told me how crowded the world used to be, before all the people went away, but we were never lonely on our remote island. We had each other, and our dogs.
Then the thief came.
He told stories of the deserted towns and cities beyond our horizons. I liked him - until I woke to find he had stolen my dog. So I chased him out into the ruins of the world.
I just want to get my dog back, but I found more than I ever imagined was possible. More about how the world ended. More about what my family's real story is. More about what really matters.
