Loving the Greek Billionaire by Lisa Swinton

She despises the wealthy. He’s the billionaire in disguise. It’ll take all the wonders of Greece to overcome their differences.
When her sister injures her foot, Rose comes to the rescue to nanny for a billionaire despite her reservations. But enduring the rich lifestyle for a month turns out better than expected when the children are darlings and the head of security grows ever more attractive. But a staff romance is against the rules.
Leo’s been posing as his head of security since his wife died and the gold diggers came crawling out of the woodwork. The new nanny intrigues him, but her prejudices against the wealthy creates an instant barrier. He’ll have to discover the source of her distaste so he can overcome it. However the deception he employs to protect himself and his family put a life with Rose at risk. Convinced he’ll lose Rose if he reveals his identity, he delays telling her.
When the truth comes out, Rose will have to choose to forgive Leo’s deception or leave them all in a bigger ruin than the wonders of Greece.
