Coffee Girl by Sophie Sinclair

Mackenzie “Kiki” Forbes finds herself in a pickle.
Either become her snarky sister’s nanny, or move halfway across the country to work as assistant-to-the-stylist of a country music star. Neither job sounds ideal, although bedazzling cowboy boots may be a hell of a lot more interesting than ironing her brother-in-law’s underwear. But life on the road as the errand coffee girl for a sold-out tour leaves much to be desired. That is, until Kiki meets her sinfully sexy new boss’s boss…
Tatum Reed’s career is flying high. He’s up for country music’s Entertainer of the Year and he’s headed out on a nationwide sold-out tour. So why does he feel like it’s all about to implode? His superstar ex-girlfriend seems determined to make his life difficult, his opening act is a handful, and the new girl on his tour, the feisty brunette, is quickly getting under his skin. In this crazy world of showbusiness Tatum needs to learn who he can trust, but that doesn’t come easily, because the one person who holds all the cards may just throw them down and walk away.
Life in the public eye is never all it’s cracked up to be, which has both Kiki and Tatum questioning what they’re really doing with their careers, and their hearts.
