Long time geek, fangirl, mother, and reader. I've got a lot to say, you might not like it all, but it will be honest and hopefully helpful.
Please don't blog only about your book. Promotion is fine, but if all you ever talk about is your book, you won't get followers or readers.
Tell us about yourself. Blog about books you like, and that you don't like. Blog about your writing process. Win us over with your personality. I can promise you that this will lead to readers, and maybe even friends.
