Gordon Jack has been a high school librarian for thirty years. In that time, he did his best to keep kids reading, including writing two young adult novels, The Boomerang Effect (2016) and Your Own Worst Enemy (2018), both published by HarperCollins. Now that he’s about to retire, he figured he should write for people closer to his own age, which is why he’s suddenly interested in the lives of octogenarian crime fighters. His funny mystery, Poppy Montgomery Gets Even will be published by Simon & Schuster in June, 2026.
