This is Love by Melissa Foster

She has everything money can buy, but her bodyguard is all she wants—and together they’re exactly what each other needs in this heart-racing romance by Melissa Foster, the New York Times bestselling author of Call Her Mine.
Actress Remi Divine is sick of bodyguards, sick of stalkers, and sick of feeling like she is always under a microscope. But this movie star isn’t helpless by any means. She’s got a rebellious streak, and she knows how to use it. First order of business: getting rid of the overbearing bodyguards who are sticking to her like glue.
Mason Swift has made protecting others his life, and when Remi ditches his two best men, he takes over and gives it everything he has. Having grown up in the foster-care system, and as a former special operative, he knows all the tricks. Nothing gets by him, especially not gorgeous, sneaky Remi.
He thinks she’s a diva. She thinks he’s arrogant. But when sparks turn to flames and their walls come down, their true hearts are revealed, and their connection is unstoppable. And when tragedy strikes, Remi realizes that being protected isn’t the worst thing in the world—but losing Mason just might be.
