Last night I finished reading Cormack McCarthy's The Road. By the time I was done, I was sobbing so uncontrollably that Kyle came running into the bedroom terrified that something really bad had happened.
The book is a post-apocalyptic story about a father and his son, walking the empty roads of America, trying to get to a safe place. The story is so incredibly sad but profoundly hopeful... A great reading experience, really.
I was so sad, though, that I immediately had to start reading an author that provides a diametrical kind of reading experience. I started David Sedaris's When You Are Engulfed in Flames: seemingly light-hearted but strange and sort of... well... disturbing.
Read both. If you are not afraid to weep, that is.
