Holly Green is an auditor with a New York firm. While working temporarily in the Dublin office, she falls in love with her colleague Oliver Conlon. Fresh out of a disastrous love affair, she now feels she can rebuild her future.

Then she comes up against corrupt businessman Ger Baron and her tough-minded tactics land her in hot water at work. It looks like she must return to New York, leaving Oliver and a lot of unresolved issues behind.

But, suddenly thinking outside the box, she makes a decision that puts her in a very strange situation indeed...

A few days later Holly is live-in nanny to two small children—a withdrawn five-year-old and a demon two-year-old—and is wishing she really did have the experience she claimed she had on her CV. Then she makes two discoveries: Supernanny—and the fact that applying her own business training may be just the thing to whip the household into shape...

Whipping Oliver Conlon into shape is another item on her agenda...
