In March, we asked you to tell us your favorite science fiction novel, film, or television show in which extraterrestrials threaten the existence of humanity. Congrats to Rob Kelly! He wins a copy of Ship of Destiny, signed by Frank Chadwick!

I have to go with Twilight Zone’s “To Serve Man,” by Rod Serling based on a short story by Damon Knight. Of all the great alien invasion stories out there, it really captured the hope and horror of first contact. It had a powerful effect on me the first time I saw it as a kid.
