Sitting on her wedding day in a tiny Texas church bathroom holding a positive pregnancy test, Darby Dixon realizes that no matter what bad decisions she's made in her life, marrying her abusive fiancé would be the worst. She could never stand up for herself, but protecting her child was another matter. With the remainder of her cash in her pocket, she escapes her past life and takes a bus to the most remote place she can afford. That's how Darby, with her beautiful smile, ends up behind the front desk of a Colorado Springs hotel. This life is not luxurious, but now she and her child are all that matter. Former Marine Scott "Trex" Trexler worked in the most dangerous, corrupt places and hot spots. Now he finally has the chance to return to the place where he last felt safe—Colorado Springs, Colorado—to begin working at a top-secret military complex hidden in the bowels of Cheyenne Mountain. The second Trex walks into the hotel , Darby understands that it is better not to mess with him. And she certainly doesn't want to get close to yet another man who seems to be filled with secrets: no matter how charming and drop-dead gorgeous Tracks is, he clearly doesn't tell her everything. But when the mountains begin to burn with wildfires and Darby's ex-fiancé reveals that he has no intention of letting her go, Darby and Trex realize how not knowing can hurt.
