The man who broke her heart is back…

But following the theft of a rare, priceless jewel and the murder of her fellow employee and friend, Maggie is suspected of complicity. Only investigator Kevin Lombard believes in her innocence. But thanks to their shared history, he's hardly objective. He must prove Maggie’s innocence… and protect the woman he never forgot from whoever is out to get her.
