Protected By the Bad Boy by Evangeline Kelly

A country singer, a bodyguard, and a mystery that ties them together.

Four years after the death of her husband, Kayla Keller’s dreams of making it big in the country singing industry are the only thing keeping her sane. When she’s attacked after a concert, she thinks a crazed fan is responsible, but a chilling phone call soon after brings up memories from the past that still haunt her. She hates the idea of a bodyguard trailing her steps, but she relents when she realizes how dangerous the situation has become.
Troy Littman has waited for a promotion and chance to head the new division of Bad Boy Bodyguards for a long time. He’s ready to put all his attention into developing the office when he’s given one last assignment: protect a country singer from potential harm. A no-fraternization policy prevents relationships between clients and bodyguards, and Troy has always maintained a professional distance. But Kayla Keller gets under his skin in a way that no other woman has.
Troy has to choose between a relationship he desires and a promotion he’s wanted for a long time. And just when he thinks he has the answer, new information pops up, putting Kayla’s life in even more jeopardy. Will they catch the man who attacked her, or will their growing love slip between their fingers before it has a chance to begin?
