I got an e-mail from a reader today that didn't like a certain aspect of the story. That is fine and I wrote a few paragraphs explaining why it was included in the story and showed specific reasons it was needed for the overall plot.
The problem was that after I sent the e-mail, it came back undeliverable. This is the same as when readers send anonymous e-mails and ask questions but we have no way to respond. Most authors write and appreciate feedback even though it is one or two out of a thousand readers that actually writes. It is great to be able to respond to both positive and negative criticism. If you expect or would like a reply please include a valid e-mail.
