The Secret Heiress

This is an Apple Books audiobook narrated by a digital voice based on a human narrator.
Finding out she is heir to a fortune shocks Caroline Tully to her core. And to "qualify" for the inheritance, she just has to visit her newfound grandfather's Mississippi home from Christmas to New Year's. Adopted as a baby, Caroline knows nothing about her mother's family…and doesn't realize they can't be trusted. When attempts are made on her life, there's only one man who can protect her. Donovan Cavanaugh—a man who made her lonely heart want to love again. Posing as her fiancé, Don promises to find the would-be killer. But will his protection—and his love—be enough to keep her safe?
