Ryder’s Watch by Kris Norris

After twenty years as a Combat Rescue Officer in the Air Force Special Warfare’s division, Ryder Callahan is ready to start the next phase of his life. Moving to West Yellowstone with his best friend Mason Quinn and the rest of his team to head an advanced security division inside the already established Brotherhood Protectors is the perfect solution. Discovering civilian life is almost as deadly as his time in the service isn’t part of the plan. Especially when it involves Kennedy Sinclair — a mutual friend of Mason’s, and the woman determined to be his undoing.
Kennedy’s smart, attractive, and far too sophisticated for a guy who prefers a man-made lean-to over a five-star hotel room. The fact she thinks he’s an ass doesn’t help his chances, either. But when a last-minute security detail at her foundation’s charity event turns ugly, Ryder quickly learns she’s not the person he thought she was.
Convincing her she needs protection won’t be easy — getting her to give him a chance to prove he’s not who she thinks, either, nearly impossible. But Ryder’s never backed down from a challenge, and he’s not about to start, now. It doesn’t matter how many armed men are hunting her, where they strike, or whether she’ll ever want more than a safe haven, he’ll go the distance. Because this is his watch, and failure isn’t an option.
