This morning I have Robert Cummings and John Simpson on my blog. They both have some solo books out, but also are beginning to grow their list of co-written books. Their latest, The Marine, is a story you won’t want to miss. I had the chance to interview both John and Robert and I got to ask some fun questions. After the interview, read all about the book and an excerpt that will make you want to read more. At the very bottom, enter for a chance to win one of two copies of the book.
