A Sound of Thunder, Paperback

In "A Sound of Thunder", Time Safari, Inc. offers the greatest hunting trips ever--any year, any animal. But they don't guarantee you'll come back, or what you'll find if you do. And in "Night Call, Collect", who is harassing Emil Barton, the last man in the universe? After decades of waiting on Mars, these twisted phone calls could kill him! Winner of a Peabody Award.
