Arthur C. Armageddon

Great book. Amazing book. Blew my mind when I read it ten years ago. What's it about? Who knows. The only thing I can remember is at the end the last man on Earth has some sorta existential dilemma. Or not. Wikipedia would know. But it has aliens, and not to ruin it, but the Earth goes bye-bye. Armageddon Wednesday in a nutshell.
