Daniel Watson by Kathi S. Barton

Working undercover was mostly all Cassie had ever known. All she had left was her brother, Bradley, who was also special forces and working undercover. Bradley had arranged to meet with her; there was something he wanted her to see, but before he could tell her anything, they were trapped in an ambush. Bradley didn’t make it, and she barely survived. The problem was Cassie didn’t want to. She had no one left…
Daniel Watson was also working undercover. This was his last gig, and he was ready to retire. He didn’t question it when his car was cut off, and he was herded into the back of a van to take care of gunshot victims. It was the nature of the beast…
Daniel was the last of the brothers that Caleb had set out to find. Daniel didn’t want his new family to be caught in the crossfire. But Caleb insisted that family is what he needed most right now…
Things were worse than they had all feared. Bradley’s secret affected them all… The roots of being Berkley’s bastards ran deeper than any of them ever imagined.
