I guess I worry about weird existential things, like how do we spend our final act. This is a very emotional question. I can't answer it without crying. I think, You're 56 years old, what did you do? You raised two good kids. What am I going to do now that is as meaningful as that? I don't know the answer yet.
Sci-Fi is the genre that explored both possibilities: the end of our existential crisis and the end of our existence. My novel, 'The 5th Wave,' explores the latter scenario, because, frankly, I believe it represents the likeliest outcome of an extraterrestrial encounter. In short, if they're out there, we better hope they never find us.
