Marriage Under Fire - Grayce Walters Contemporary Romantic Suspense, #4

Marriage Under Fire is book 4 in the Grayce Walters contemporary romantic suspense series set in Seattle by USA Today bestselling author Jacki Delecki. Each book is a standalone, steamy, fast-paced romance with a guaranteed happily ever after! Marine veteran Maddy Jeffers never expected her most demanding and daunting mission would come off the battlefield. Ordered to infiltrate a Seattle terrorist cell, Maddy must pose as a loving wife to Major Hunter Hines.
The undercover role begins to feel all too real when Maddy falls hard for the rugged, macho Marine. Duty and discipline are Hunter Hines's credo, guiding every decision and every action. But constant proximity with the fierce and enticing Maddy is veering his mission wildly off course. Although their role as man and wife is only pretend, there is nothing false about his out-of-control desire for his partner.
When Maddy's life is threatened by an ISIS cell, protecting her becomes the only mission that matters, and Hunter is willing to break all the rules to save her. As the danger heats up around these two veteran heroes, Maddy and Hunter must walk a narrow path between passion and survival.
