Redneck P.I. by Trish Jackson

Twila Taunton hates living in Yankee territory and has vowed never to allow a man into her life again. Everything is turned upside down when she invites hunky P.I. Harland O'Connor to the company picnic and she looks into his bedroomy eyes. Even worse, his equally as hunky twin brother makes her overlook her cop allergy. Twila finds herself ducking bullets, and when Harland is wounded, she steps in to pinch-hit for him. Her lack of city-sophistication and disregard for political correctness help her solve some tough cases. And then someone tries to blow her up. She and Harland are soon caught in a dizzy, dangerous tangle that could cost them more than their lives.
