If you’re ever reading one of my novels and come across a mistake, feel free to let me know. One of the great things about Kindle and Nook (and the other e-formats) is that I can go in and make corrections. Granted, that won’t help you, but it’ll improve things for future readers.
If you spot a spelling mistake of the kind we all love (the spellchecker doesn’t catch it because “their” is spelled correctly when the word in the sentence should be “there”), I won’t mind a bit if you let me know. If you think I had the wrong person talking, let me know. Just send me the sentence and let me know what’s wrong with it. Send it to firstname.lastname@example.org
This is what Mark Twain did with “Huckleberry Finn”. As people told him about problems, he used his profits to pay for a re-write and re-publish.
