Mr. Billionaire by Ivy Jordan

Stella left her last nanny job because the father got handsy with her. As such, the attraction she feels for the father of her new job rattles her. Her unease only grows when he explains that her job is not only to be his daughter’s nanny, but also to pretend to be his girlfriend.
But when he explains that she will receive a salary of one million dollars a year, the prospect seems a little less daunting.

Of course, this begs the question, why would a wealthy man want—or need—to pay a woman a million dollars a year to pretend to be his girlfriend? Is this going to be a dream job, or a waking nightmare?
