my reading book

The book I am reading is called The Mist by Stephen King. In this story a vicious storm attacks the city and the storm turned out to be harvesting a mist. This mist had a certain power to it that created creatures, but nobody knew about these creatures until later on in the book. After the storm, there was a blackout that was in effect for three or four days, and thinking that the blackout would last much longer, everyone went to the supermarket to stock up on food. While at the supermarket, people noticed that the mist was rolling into the city rapidly. The mist was so thick you could not drive through it, so people decided to wait out the mist at the store. One courageous man tried to get to his car so he could get back to his family, but before he could reach his car, he came running back to the store screaming, saying he saw some sort of sci-fi creature. No one believed the man, they all thought he was crazy. But it turns out that all the scare was for a good reason. A little bit later in the book, the store gets attacked by these mist creatures. Fighting for his life and others in the store, David and a couple of his buddies fight off the mist creatures. Will they come out alive?
