Ranger Integrity by Lynn Shannon

Framed for murder…

Private investigator Sienna Evans is searching for a missing woman when a tip leads her onto a boat with a dead man. He’s been shot with her gun, and the police believe she’s the killer. Arrested and charged, Sienna is shocked when she’s bailed out of jail by her ex-fiancé, Eli. She hasn’t seen him in five years, not since he walked away from her and their relationship.
Texas Ranger Elijah Goodwin doesn’t give second changes. His childhood taught him a strict adherence to the rules leads to success. Failing in love with Sienna was the only time he deviated from doing the smart thing—and it blew up in his face. Still, when he discovers she’s been charged with murder, nothing will stop him from coming to her defense. The infuriating woman is many things—gorgeous, brave, and stubborn—but she’s no killer.
Digging for answers thrusts Sienna and Eli into a case with far deeper implications that either anticipated. As the threats increase, Eli vows to keep Sienna safe, but protecting her may cost him everything. His heart. His career. Even his life.
