So I'm writing a story, and I'd like an opinion. Not on plots, but on something about a character. See, the main character is a woman who gets swept up in this crazy murder mystery/supernatural crap. There's just one tiny little problem with my plan. Will the readers buy it if they don't know her motivation? The first part of the book, she doesn't get a choice. I have a nice character establishing moment and a hook in chapter one. But beyond that, and beyond one line, she doesn't bring up why she's doing this. It will all come out later on, as she slowly works through the plot. But, until then, will readers buy that she's doing this crazy thing without knowing why, especially when she doesn't even know what she's doing? And without being given a good reason as to why she's doing these things?
