A story can include one of two things: flashbacks or skipping to the future. We don’t think recommending the two is a great idea but if executed cohesively…sure! Why not! Let’s discuss.
Sometimes, writing flashbacks can help a story flesh itself out. Readers understand the plot better, the character better, ANYTHING! But what happens when a flashback becomes more than a flash back? Meaning, what happens when a brief moment takes up a whole chapter? Is that acceptable? There isn’t any reason why it shouldn’t be acceptable – other than not being written properly. Make sure flashbacks are quick and easy. They’re meant to be memories triggered by people or items or occurrences surrounding the character or plot. Here’s an idea: it doesn’t necessarily have to be written in the perspective where the character is brought back to a moment in time…but rather, induces a feeling, an image flashed in the character’s thoughts. Something like that.
Skipping ahead in time is also a way to get the story moving along. Readers don’t need all filler details and a story doesn’t deserve that either! A few months can pass in the story in a matter of words, as long as the reader is caught up with the characters and ongoings in their world, what else is needed? Questions should never be left unanswered, too. If they are, there better be good reason for it. Did something happen prior to the time hop that wasn’t resolved during the time not mentioned? Well, it better come full circle because then the reader will not be happy (they’ll scream, “PLOT HOLE, PLOT HOLE!” and write a whole review about how the plot hole ruined the story for them.)
So, now that we’ve lectured about time and the relationship it has with your story – let’s build a time machine and have some fun!
