It's an amazing book but be prepared - The Road is very dark and unsettling. Not exactly a swashbuckling, hopeful, "let's band together to rebuild" type book.

It has extreme deprivation, depravity, and collapse. It's an unblinking look at humans scraping out their survival on a day-by-day (sometimes hour-by-hour) basis in a brutal, zero-sum world.

Closest comparison imo is Night by Elie Wiesel.
