I'd never read a James Patterson book before. He is a <a href="https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQBKdHv_OVffL1HK09rTqj1JmIeQdTH1H_SyLBNU0bcbFFMt-EM5BMunko_D3xsxm93JeY&usqp=CAU">joke in library circles</a>, so my choice was more about Dolly Parton than JP. Sorry to report that the book was absorbing and sweet. I assume the former was JP and the latter was DP? 

The protagonist, AnnieLee Keyes, is a singer-songwriter absolutely bursting with talent, beauty, and star quality, but maybe the combination of fierceness and vulnerability that makes her so charismatic comes from her past, which she doesn't talk about, except to lie. 

Her love interest, Ethan, is a talented guitarist and her mentor a Dolly Parton stand-in named Ruthanna. They both have sadness in their pasts, too. Still, everyone puts aside their own traumas to support AnnieLee. Though I believe Patterson is known for writing thrillers, this is much more of a romance, with sprays of violence and one cross-country car chase.
