Query: They Just Don't Write 'Em Any Better!

What can I say about Richard Matheson that hasn't already been mentioned here. He's great. He's amazing. He's a master at his craft and nothing exemplifies that more than his novel "I am Legend."The first time I picked the book up, I couldn't put it down. And when I got to the end, my throat constricted and a tear almost--I said almost--appeared at the corner of my eye. When words on the printed page can do that to you, you know you've found serious talent."I am Legend" belongs on any serious sci-fi or horror fan's bookshelf. I'm getting a chill up my spine just by writing this review.I'm going to stop now.
