The Billionaire's Duty

Are our secret billionaires hiding more than money?
Cross Ronstein could be described as a lot of things. Mining magnate. Domineering Boss. Secret Billionaire. He doesn't care what he's labelled, even when the tax office takes an interest in his business. Their attention is of minor concern until he lays eyes on the temptress sent to dig into his affairs.
Maybe he can turn the secret billionaire's game to his advantage, just like his friends have done.
Jessa Collins has her own array of labels. Tax Investigator. Firebrand. Discoverer of Secrets. Whatever people call her, she gets the job done. Every. Single. Time. Even when her target dismisses her suspicions as fantasy and promptly leaves the country for a made-up obligation.
No matter what drastic measures Jessa has to take, this rich businessman is NOT getting away while she's on the case.
How far is too far to follow a secret billionaire? Can two people on opposite sides of the corporate fence find their way to love?
