This aspiring author wishes to inform any who follow these postings that the 4th book in The Kinsman Series, "Exploitable Weaknesses" has just been published through Kindle Direct Publishing and should be available through Amazon/Kindle within the next 72 hours (following the obligatory Review).
Once it has been added to Goodreads' book list, I'll get it associated with the other 3 books, for simplicity.
Thank you for our interest.
