New Shiver and Fears

So those who are wondering, yes, there is another Shiver and Fears book coming out. It's making small progress. It's been worked on for a few months and I'm having a little trouble. No spoiler, just know there's a thief on the loose and two strange new neighbors. Now you might be thinking 'Oh of course, the new neighbors ARE the thieves. No, not at all.
So what's the hold up? The answer is a little writer's block. This next book will host the original 20 chapters and the complex is around the revealing of the plot... So what's the issue? The problem is, how to plot the rising action before revealing anything in the complex. Not to mention, relating details in the rising action to the complex.
For those of you who might not understand author vocab, let me explain my problem another way. You see, I want parts of the story to relate to the problem of the story. And it has to make sense. Like in The Ghost Next Door: How Hannah had that dream about a fire, and why her family was nowhere in sight... SPOILER ALERT She's a ghost! Killed by the fire (she wasn't dreaming).
A Puppet Family is about a boy making friends. That's all you get from that! Someday it'll be published. Just need to figure out chapter 6.
