Since some early ones have come in for Demon's Fall, here are some scattered notes from the author's point of view on reviews:
I do read them. I have a thick skin and a short memory. I think because my older brother is also a writer (and he's not the type to just gush over everything), I grew up dealing with a sharp eye on my writing. (My mother is also the type of person who will take the time to gently explain how to improve children's artwork directly to the child. This is not cruel; it's born of a genuine desire to help the next effort be better. I prefer this kind of forthrightness to polite flattery.) My books are not my children, and I know some people won't like them. Won't stop me from writing 'em.
My policy is not to comment on reviews; I'd like to say thank you, but I'd rather the reviewer not feel hounded by the sense that the author is watching him or her. The exception will be if I requested the review.
Requesting reviews is mildly nerve-wracking. It's like the submission query all over again, except that editors are probably going to start reading your story to give you a chance. Reviewers get to be pickier about what they'll actually open.
I would like to gather up reviews as research data for any potential readers. So some point soon I'll add auxiliary pages for my books to link to reviews — negative ones too, as long as they're well-written. If someone is unlikely to enjoy reading one of my works, I'd rather he or she discover that before buying it.
I do learn from reviews! Criticism, when it's well-explained and not based on a personal bias (and that's what makes a reviewer more than just a reader with an opinion, right? —that self-awareness and articulated reasoning), is constructive.
Grades/stars/a number of random symbols don't mean near as much to me as the qualitative review.
I do have favorite reviewers, based more on their writing style than their taste. Okay, and the cleanliness of their sites.
Google Alerts are a time-saver. And learn the advanced operators if you don't already know them.
It's particularly fun to learn which secondary characters caught people's interest, or if more stories in the same setting would be welcome. And it's amazing which other books and authors you'll get compared to.
