Montana's Way — Shelia M. Goss

Montana Blake and her sisters, Savannah and Asia, teamed up with security professional Troy Bridges to bring their father's killer to justice. Along the way, Savannah and Troy fell in love, and Montana is overjoyed that the two are headed toward marriage. Suddenly, Savannah and Troy vanish...and a surveillance camera reveals they were abducted from their home. Troy's partner, six-foot-two Sean Patterson, joins the sisters in a rescue operation. Sean has met Montana before, and he's never been able to forget her. He's not the settling-down kind, but Montana may get him to change his ways. That all depends on whether they get out of this alive--because the kidnapping is only the first move in a vicious plot that endangers all of Dallas.
