The best way to thank an author is to write a review
You can support me in numerous ways, of course in the first place by buying my books. If you read a book, be sure to leave a review at Amazon and at your favorite social network. Share my stories with your friends, mention them in your blog, buy them as a gift for that special someone. Feel free to contact me with any questions, suggestions, or remarks you might have. All feedback is well appreciated.
