The Nanny and the Boss's Twins

Stacey is a nanny, and her new boss is handsome workaholic and company president Luis. As a single father, he’s hired her to look after his twin sons during their three-week trip to Spain, totally expecting her to be unable to handle the two six-year-old rascals because she’s so young. When it turns out she’s actually very good at her job, Luis finds himself becoming attracted to the bright and open-hearted Stacey despite his tormented past. Source: Harlequin
