I just finished reading The Dog Stars by Peter Heller, a beautiful book about a man named Hig and his dog, Jasper, who survive a pandemic outbreak that kills most of the population. He loses everyone and fights to survive in a lawless world. He struggles with the meaning of his life and if it is worth living.
The video below is from Peter Heller's website and provides a nice trailer for the book.
I'm an expert amateur or maybe an amateur expert.
