All Harley wanted was her freedom. She had enough family drama of her own, living with her unbearable stepmother and her stepsisters. The last thing she needed was more. When she gets a job nannying for one of the most influential families in Boston she thinks she's in the clear, but when the news comes that Boston's most eligible bachelor, Ben Buchanan, is up for grabs she unwittingly finds herself in a story worthy of Cinderella. At the request of Ben's estranged mother, Harley agrees to play the spy for her and attend the parties while trying to keep Ben from figuring out she's his little brother's nanny in disguise.
