I’ve been keeping an eye out for new work from Lynette Nusbacher for a while now. If we're talking strictly about traditional book releases—the kind you'd find on a bookstore shelf with her name as the primary author—there hasn't been a major new title in recent years. Her most well-known works, like 'The Battle of Bannockburn 1314' or 'War and Conflict', came out in the 2000s. Her focus seems to have shifted quite a bit towards her other career in military analysis and media commentary, which is where you'll find most of her recent public output, like articles, lectures, or TV appearances.
That said, if you’re a completist, it’s worth checking if there have been any new editions or reprints of her existing books with updated prefaces. Sometimes a publisher will reissue a work with a new cover or a brief new introduction by the author, which can feel like a fresh release for fans. But a brand-new, from-the-ground-up book on military history? I haven’t seen one announced. My search usually ends with me rewatching one of her old documentary segments on YouTube instead.
