Public Relations (my day job) can be a funny little world, because if you do your job well, no one sees you. Your name doesn’t appear on article bylines, your face isn’t the one on camera, you aren’t the one giving high-profile testimony.
True, you’ve a) organized the opportunity, b) written the articles and scripts, and c) coached your client on how to handle it. But the whole point of PR is that the spotlight shines on your clients, while you smile knowingly in the background off-stage.
In some aspects, novels work the same way. Your name is on the cover (yay!) and you get to do fan interviews and book-signings (double yay!), but aside from that, your “author personality” shouldn’t be visible on the page.
Your characters should speak for themselves without any forced commentary or viewpoints from you. Readers will see right through any heavy-handed agendas you try to weave in, and it’ll likely be a turn off for them.
Don’t feel like you can’t be opinionated in your novel, just realize you’re best served by letting your characters do the talking…and get the recognition. The best authors can make us forget we’re merely reading a book, because their voice disappears completely to allow their characters to come fully alive.
