One week with one little girl—an angel, according to my staffing agency. Acting as the short-term nanny for a single dad should have been an easy way to make some extra cash. Until I show up for my first day and face off with a demon disguised as a seven-year-old girl wearing a red tutu and matching glitter slippers.

Oh, and her father? My temporary boss? Maddox Holiday. The same Maddox Holiday I crushed on in high school. The same Maddox Holiday who didn’t even know I existed. And the same Maddox Holiday who hasn’t set foot in Montana for years because he’s been too busy running his billionaire empire.

Enduring seven days is going to feel like scaling the Himalayas in six-inch heels. Toss in the Holiday family’s annual soiree, and Christmas Eve nightmares really do come true. But I can do anything for a week, especially for this paycheck, even if it means wrangling the naughty, impressing the nice, and playing the nanny.
