Alright, I'm working on the dreaded synopsis. I'm also trying to keep it under 500 words, as that seems to be what most people in the YA fantasy realm are looking for (short one-page synopsis). So, here's my issue. I have a twist at the end of my book. Now, to be able to properly explain this twist (make it not feel like a deus ex machina), I'd be forced to include a couple of additional subplots in the synopsis. However, if I were to do this, it'd most likely put me way over the word limit(s) and maybe make the synopsis feel more clunky and explanatory.
So, do I leave out the major twist of the book to keep with the word count, or do I go back to the drawing board and try to find a way to organically include all the information in the synopsis without losing the flow and destroying the length? Would it severely turn off an agent to read a synopsis, then see a twist ending not mentioned (even though the ending, and basic plot points are all mentioned)? Any advice would be a massive help.
