AWOL

Would it be acceptable for a novel to write the following sentence?

"If she couldn’t find him, then she would officially consider him to be AWOL."

Or would I need to say something other than AWOL? Such as a betrayer or something of that nature. (The characters in my story are currently trying to find a Vampire who commited a serious illegal crime.)

In general, it's best not to use abbreviations in your writing because not everyone will be familiar with those abbreviations. If you can substitute "AWOL" for something that works equally well or better, I suggest you do.

Okay, thank you for the advice. I'll change that when I work on my story next.
