Stone Cold Texas Ranger

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
A Texas Ranger puts it all on the line for a woman who has everything to lose 

Texas Ranger Vaughn Cooper doesn't need or appreciate the "help" of some frivolous civilian on his case. Yet even this seasoned lawman can't argue that Natalie Torres is on her game. She might even unlock the answers he needs to crack this kidnapping…if the bad guys don't erase Natalie first. 

With her home burned to the ground, Natalie has no choice but to hide out with Vaughn in a remote cabin. Spending time with the stone-cold officer should keep her mind strictly on the case. But there's an unseen fire burning deep within Vaughn, and it's making Natalie wonder just where the true danger might lie.
