Finn needed a stand-in mommy for his little girl. He got a stand-in nanny! They needed a nanny... When millionaire Finn Helliar walked into her nanny agency looking for help, Caro couldn't believe her luck! This was the man who'd hurt her sister and what better way to make him pay than to accept the position he was offering? ... and look what they get!

Unfortunately, Caro had reckoned without two things: Sophie, who was adorable, and Finn - who was even more adorable! The more time she spent with them, the more she realized her plan had one fatal flaw... how could she ever leave?
