When I signed up for the nanny agency, I didn’t expect a remote mansion on a windswept cliff. Or a brooding billionaire. His brother’s death means he’s the guardian of a moody seven-year-old-girl. She’s lashing out at the world, but I can handle her. I have to. I need the money to finish my college degree. As long as I can avoid the boss who alternately mocks me and coaxes me to reveal my darkest secrets.
