Inner Logic of Sci-Fi Stories

Readers, we’ll believe any fictional world a book describes, but once that world is established, the author can’t change the rules of the game. Whatever the crazy world a sci-fi writer can come up with, it has to have an inner consistency that can’t be broken.

In a story about an alien invasion you might be willing to accept the fact that aliens just landed on your backyard, but you would have a hard time believing unlikely behavior, such as the possibility that said aliens have fallen madly in love with you.

So don’t lie, and keep your stories consistent.
