A love psychologist needs a husband to prove she's not a quack. A billionaire prince is the perfect mail-order groom.


Dr. Deanna Pearson's love algorithm can predict if a marriage is going to last forever. When she's challenged to get married herself, the divorced doctor must face her fear of marriage. After she's matched to a cocky billionaire prince with commitment issues, Deanna wonders if she's made the biggest mistake of her life. Until the honeymoon on his private jet stirs repressed feelings yearning for release.



Business mogul Prince Maxim Malenkov isn't afraid of commitment, just marriage to the wrong woman. He thought he was safe in America until his brother, the king, appeals to his sense of duty. When Maxim hears a reality TV doctor needs a husband, he can't resist one final act of rebellion. After their wedding night ends with them sleeping apart, Maxim will do whatever it takes to make Deanna feel safe and wanted.


After a night alone in an abandoned farm, Maxim and Deanna agree to make their marriage work and revitalize his country's economy. But if they can't get the king to accept her, they'll have to dissolve their union. And when palace intrigue threatens Maxim's family and Deanna's reputation, will their budding romance last?


Her Spare Heir Billionaire is a standalone novel in the Billionaire Boss series where the men have the money but the women make the rules. A sexy billionaire prince, quirky best friends, and toe-curling kisses are what you'll read in this contemporary, palace intrigue romance by Eliza Ellis.
