Welcome back! Let's return to Charlie Jane Anders (author of All The Birds in the Sky) and #2 of her "10 Writing "Rules" We Wish More Science Fiction and Fantasy Authors Would Break"...
2) No prologues
This is one I’ve been
hearing for years — some agents and editors say they stop reading
immediately if they see that a book has a prologue. But prologues have
their uses, especially if you want to set a mood or establish some
crucial backstory before you start introducing your main characters.
Like most of the other things on this list, prologues can be done well,
or they can be done horrendously. Luckily, we don’t have to reach far to
think of an example of prologues done well — George R.R. Martin starts
every one of the
Song of Ice and Fire books with one, and it’s
clear why these prologues are there. They help set up the conflicts of
each book, via the experiences of a throw-away character. (Literally, in
fact.)
And you may have noticed that whenever literary writers tackle science
fiction or fantasy, they include tons of infodumps? Maybe this is one of
those instances where they’re not as familiar with the genre
conventions, and thus fall into habits that many “real” SF and fantasy
authors would avoid — but in this instance, they may just be right.
Sometimes you just have to explain something, as painlessly as you can.
