My biggest gripe with this story is that Mia is 22-years-old but acts/thinks much younger. I wanted to reach out and shake her and tell her to stop acting so insecure. This is particularly irritating since she presents herself at the beginning of the story as a professional, taking over her father’s car dealership with all its attending responsibilities. I know that young professional women can be basket-cases of insecurity inside, but that doesn’t stop me from wanting to shake those same women in real life! Ms. Evans’ biography says she is the mother of a daughter, so I desperately hope that her future heroines will present with more self-confidence. My other tiny complaint is that the parents of said 22-year-old are made out to be nearing retirement and in need of careful handling. Sigh. That said, the story was interesting and flowed well, the surroundings were expertly conveyed (be it the Tennessee heat or the beauty of the underground caves), and BB (book-boyfriend, a nickname Mia uses internally when she first meets Derek), is most definitely swoon-worthy and deserving of the name. I was given this free review copy audiobook at my request and have voluntarily left this review.
