Hell Bent. Deep Six Security Series, #3

Former Delta Force Operator turned CIA Ghost Ops Operative Cade Winters has been dodging his dysfunctional family for years.  He isn't supposed to have a family, it's too dangerous, but Cade can't let go of the only person he gives a shit about, his sister Veronica.  When he makes his yearly call to her and finds out she's receiving death threats from a homegrown terrorist group, Cade knows he has no choice but to go back to Texas to make sure she's safe.
Fresh out of a six-year hitch in the Army, Cee Cee Logan thinks she's finally earned her brother David's respect when he finally offers her a job with his security firm.  She quickly sees that isn't the case when the job she's hired for turns out to be that of the team secretary, a nice safe, desk job like he told her to get when she graduated college.  Cecelia is frustrated, but takes the position because she is determined to prove to her chauvinistic and overprotective sibling once and for all she's capable of so much more.
By the end of the first week, Cee Cee wishes she'd have just re-enlisted.  Her body is stiff from sitting, her fingers sore and her mind numb, but what really makes her want to run back to Afghanistan where she would at least be respected by her colleagues is the company's other new hire.  Cade Winters, her ex-lover, is back in town and the hardhearted, hard-bodied operator is a man she definitely doesn't know anymore. When a trafficked woman's repatriation clinic is attacked, and Cade's sister Veronica, a judge, is in grave danger, Cecelia is presented with her opportunity to prove herself as an agent.  But the question was, did she want it?  Could she trust her partner to have her back when he seemed to be on a mission of his own to put a knife in it every chance he got?
