Crossfire Creek Protector by Delores Fossen

When Deputy Laney Sutton discovers a homemade explosive in rural Redwater, Texas—a bomb nearly identical to the one that killed her husband, David, four years ago—she knows the past she’s fought to survive isn’t finished with her. David’s death was ruled a random act of violence, but the device in front of her says otherwise. Someone has returned, and this time they are targeting not only her but also her daughter.
Crossfire Ops operative Harlan Creed made a vow the night David died: to protect Laney and the baby she carried. Now, danger has brought him back into her life, forcing them into a deadly game with a relentless enemy. As bullets fly and secrets unravel, Laney and Harlan find themselves fighting side by side—and drawn closer by a heat neither expected. But to claim a future together, they’ll have to survive the killer who wants to destroy them both.
