I've been published since 2009 but I've been writing for a lot longer. Over the years I've accumulated various items of wisdom from all over. Third Tuesday Writing Tidbit will showcase these items one at a time in no particular order.
Change the resolution of a beloved theme at your own peril.
The plot should resolve in the final part of the book in a way that is unexpected but clicks for the reader. Twists, variation and conflict are great except when a) they aren't connected in any way to what's happened or b) they run counter to a theme embedded deep in the reader's psyche.
Example: "There's no place like home" resonates with purity and simplicity for anyone who's seen or read The Wizard of Oz. You can change that but be prepared for the resolution to ring false for many of your readers.
