So we've made it to the last few paragraphs of our synopsis. Like the beginning, the end of the synopsis has to accomplish a lot of different things. It needs to:
Give us the black moment.
Show how the characters changed.
Include how all elements wrap up, including spiritual, mystery, and/or romantic.
Give a satisfying resolution.
The point right after the black moment is equally important. When we're reading your synopsis, we need to know what action the main character takes that turns everything around. And it must be an action by that character. You can't cheat by using a coincidence or letting another character do the dirty work. How does the character who just lost everything begin to change things?
This is also a good way to demonstrate how the character has changed. The way the character reacts to the black moment at the end of the book is going to be very different than how he or she would have reacted to the black moment if it had taken place at the beginning of the story. Show us that difference.
Make sure you wrap up any threads that you've included in your synopsis. This is one of the reasons you should keep the subplots and minor characters out of your synopsis. Anything that you mention needs to be wrapped up at the end. You can't tell us about the sister's custody battle and then not give us the resolution to that storyline. The more you stick with the main story the tighter your synopsis becomes.
That leads us to the Satisfying Resolution. Always tell the ending. Don't leave it a surprise as a way to entice editors and agents to request the full manuscript. They don’t like that. ;) If you're writing romance, you usually need a happily-ever-after. That's not true for all genres, but you do need the ending to be satisfying in some way.
