This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
AROUND-THE-CLOCK PROTECTOR 

Despite the threats against her life, Danielle Barclay thinks having a bodyguard is unnecessary. Or at least that's what she tells herself before meeting Jake Rabb. A former Delta Force soldier, Jake is used to rope-lining from helicopters into enemy territory—not following around a senator's daughter. The lovely deputy district attorney is as strong-willed as she is brave, especially when the escalating danger assures Jake that her stalker means business. As the attacks become personal, Danielle finally puts her trust—and her feelings—on the line with her defender. But how will Jake protect her if the stalker is closer than they think?
