Pay no attention to that author behind the curtain!
If I've done a good job I will remain invisible. I'll be a name on the cover page, but the characters will have a life of their own. My favorite critique comments are the ones where the crit partner is speaking directly to my character. I'll paraphrase my favorite: "No! No! No! No! Don't do it!" Then I know I've done my job.
So how? How do I take it from forced to engrossed? The first step is identifying the "device". One way is to have critique partners look at it. I wouldn't have seen it on my own. Another is to put the book away for a while so you can see it with fresh eyes. You hear these things over and over because they are so important. And they work.
The next step is to ask yourself what would make that action feel natural. Remember it's key to understand that your character is used to her life. That she knows the contents of her room for example, or that her brother is going to be annoying. It may be a surprise to the reader, but it isn't necessarily to your character.
Also, remember there's no such thing as coincidence. If you're writing a mystery, the killer should be someone we know, but that doesn't mean the MC should realize that. It's too convenient. There has to be a reasonable explanation.
Have you run into this problem? How did you handle it?
