Anyone writing a novel should always remember: consistently consistent. From the basics like character names to heavy lore details that provide rich world-building.
Telling a linear story will make you, as the writer, feel better about your product. You’ll feel encouraged to share your story more so than before.
In order to write consistently within the words, planning is necessary. We are definitely a broken record when it comes to this topic, but that should prove how important the process of planning out your novel really is. We’re talking plot outlines, world outlines, character bios, etc. All of these are needed to create the base of your novel. If you’re not incorporating mapping time, you’re not going to write a consistent story. You’ll end up writing ten different inconsistencies and your book will never see a virtual shelf. Ever. If you need to research, take time during this stage of your writing to get the gist of it. Relating your world to the reader’s will build the bond everyone wants to have with their favorite books.
Once writing has begun to unfold, your writing style for the novel at stake should remain relatively consistent (unless it’s part of the storyline…then do what you must! Just do it in a cohesive manner.) Tone with the narrator and characters shouldn’t change throughout the novel unless tragedy strikes and alters their perspectives. The plot can change slightly, as you uncover more during the writing process, but if it’s drastic…return to your outlines. You can easily incorporate these new changes in your story; it’ll also help you see where the changes will begin to morph the rest of the tale and avoid any inconsistencies!
