How The Sigma Menace Began
Marie Johnston, an award-winning author and RITA® Finalist, launched The Sigma Menace in 2014 with Fever Claim. A former microbiology enthusiast turned romance writer, Johnston crafted this series to explore the primal allure of shifters while weaving complex emotional narratives. Inspired by her love for paranormal romance, she built a world where wolf shifters, known as the West Creek Guardians, protect their kind from a sinister organization called Sigma. Her goal? To create fast-paced stories that balance spicy romance with gripping action, and she nailed it.
Johnston’s transition from scientific writing to fiction wasn’t without challenges, but her dedication paid off. The series’ debut as a free Kindle book drew thousands of readers, sparking a loyal fanbase eager for more of her addictive storytelling.
