Query: Execellant book

This is one of my favorite books of all time, I have probably read it five times. The story line is very easy to follow. It's about a man turned insomniac after his wife dies that starts seeing things, these things turn out to be wonderful real life visions that the rest of us just can't see. I recommend this book even if you are not a Stephen King fan.
