Bought By The Billionaire Prince by Carol Marinelli

Luca Fierezza is a rogue and a royal rebel. Shunning regal protocol, he turned his hand to business, and now he's made Niroli a magnet for the rich and famous – and himself a billionaire.

Megan Donovan is stunned when she's thrown in jail after only one night working at Luca's casino. Surprisingly her unlikely rescuer is her new boss, Luca! But at what price?

The Tycoon's Princess Bride by Natasha Oakley

Outwardly, Domenic Vincini's physical beauty is marred by scarring. Inwardly, he seems driven by a need for power... Princess Isabella Fierezza has based her career on helping the island of Niroli prosper, and Domenic threatens that. Worse, she can't be in the same room without wanting him! But, as an heir to the throne of Niroli, Isabella must marry for duty. If she gives in to temptation – and Domenic's seduction – she will forfeit her claim to the crown...and risk tying the kingdom to its sworn enemy!
