Readers are savvy! We need to tell a story without filling in every minute detail. If the author develops a character with enough precision, the reader can discern that character's motivation.
Since you promoted my books on your website I have noticed a marked increase in sales. Since I have not recently done any other promotional activity, I have to assume that this renewed interest is directly attributable to Humanmade. I simply want to express my gratitude once more and to thank you for the work you do."
