Sophia, I’d encourage you to see book promotion more clearly. You’re not tooting your own horn. You are sharing information about your book, not talking about yourself. You wrote your book for a reason — to entertain, enlighten, educate, or even offer hope. You can’t help people with your message — whether you write fiction or nonfiction — if they don’t know about your book. Don’t you owe it to the people you wrote the book for to help them discover it?

Thanks, Karen! (And your check is in the mail!)

For your next book, start early by engaging readers in the process — recruit beta readers, ask people to vote on cover options, get their feedback on character names or book settings, etc. Help them become attached to your writing in a way that’s genuine for both them and you, so they can become your advocates when the book is published.

I suspect that building relationships with booksellers and librarians comes easily for you, and that you’re very good at hand-selling your books.

Thanks so much for sharing your experiences and validating this idea that we can all learn from the successes of others!

Sandy
