The Billionaire's Chauffeuress - Clean Billionaire Romance, #4

She wasn't supposed to fall in love with the billionaire in the backseat.            She was just supposed to drive. Isaac Cooley goes to work and goes home. He's keeping his nose to the grindstone, trying to make up for a reckless past. Whitney Ames is his housekeeper, and he doesn't even know her name. But he learns it quickly when the chauffeur position opens up and she jumps to fill it. They're just getting to know each other when a little girl shows up on Isaac's steps, claiming to be his daughter, which isn't possible. Or is it? As the unlikely threesome struggles to make sense of their new circumstances, Whitney becomes more and more worried about the dangerous feelings she's developing for her boss.
She shouldn't be having such unrealistic dreams, should she?
