Interesting question! I guess I'd want my readers to be moved by the internal journey that my main character, Hannah, takes. And to love her as much as I do, as flawed and stubborn as she is.
My ideal reader would be one who likes to watch characters evolve -- that's important, I think. Hannah's arc is kind of a slow burn -- after the initial attack, we've got some slice-of-life stuff that gradually progresses into an unfolding of mysteries and finally explodes into... well, spoilers. So my readers need to be people who enjoy that progression, that stacking-up of mysteries and plot points for rewards that happen as the novel develops.
The flip side to this is that people who are looking for a lot of action and drama right away aren't going to be satisfied. It's the people who find themselves invested in this silly, unlucky kid and want to watch her grow up and start to own her life and her decisions who are going to like this book. People who love a strong character arc. People who like to try to figure out hidden truths and mysteries before they're revealed. That's the kind of reader I am, and it's definitely the kind of reader I write for.
