From Amazon.ca:

Violence, in McCarthy's postapocalyptic tour de force, has been visited worldwide in the form of a "long shear of light and then a series of low concussions" that leaves cities and forests burned, birds and fish dead and the earth shrouded in gray clouds of ash. In this landscape, an unnamed man and his young son journey down a road to get to the sea. (The man's wife, who gave birth to the boy after calamity struck, has killed herself.) They carry blankets and scavenged food in a shopping cart, and the man is armed with a revolver loaded with his last two bullets. Beyond the ever-present possibility of starvation lies the threat of roving bands of cannibalistic thugs. The man assures the boy that the two of them are "good guys," but from the way his father treats other stray survivors the boy sees that his father has turned into an amoral survivalist, tenuously attached to the morality of the past by his fierce love for his son. McCarthy establishes himself here as the closest thing in American literature to an Old Testament prophet, trolling the blackest registers of human emotion to create a haunting and grim novel about civilization's slow death after the power goes out.

McCarthy's novel is the ultimate story of parenthood, fatherhood, friendship and survival at all costs. Heart wrenching at nearly every turn, it's hard to imagine things getting any worse, or any better but the story keeps moving ahead with the reader along for the ride because ultimately, we want to know what happens. Occasionally I had to take a moment between passages because the mental images were so difficult to take and because of that, I was surprised by the last few pages of the story.

An amazing read that is certain to sit with you, even after you've turned the final page.
