2000 Book Challenge Jun 21, 2014 | Uncategorized | 1 comment Now that all three of my books are available in paperback and e-book formats, I’m hoping to reach that Wheatmark Publishers ‘ goal of 2000 books sold! All are available through www.amazon.com and www.wheatmark.com. 1 Comment Consie Richardson on June 22, 2014 at 12:53 pm Great goal, Duke. My hopes are with this month’s ad, along with 90-something other Harvard authors, in the June/July Harvard Magazine, with a circulation of 240,000. Good luck!
