Loving Bea by Cara Carnes

She’s a magnet for trouble…
After they saved her from a violent marriage years before, Bea Stanz made a vow to fix her own problems and not rely so much on her brother and his fellow operatives at Counterstrike. Her newfound independence has been far from easy, but Bea 2.0 is determined to handle whatever comes her way. When a simple errand exposes a dangerous international kidnapping ring, she turns to the one man who’s taken her protection as a personal mission.

He swore to keep her safe…
Joe “Hazard” Santos left military service and joined Counterstrike after they rescued his sister. Protecting innocent women and children is his new mission, one he won’t fail. The beautiful, impulsive, and passionate little sister of a fellow operative is a task—one who blew into his life like a hurricane. He’ll do whatever it takes to keep her safe, even if she doesn’t want his help.
They will need every resource at their disposal to face this threat, but will all of Counterstrike and a Delta team be enough to succeed?
