Undercover Billionaire: A spicy forbidden love billionaire romance from USA Today Bestseller Amy Andrews for 2025

Cocktail waitress Kelsey Armitage needs her job on board the Callisthenes cruise ship. Nursing a broken heart and an empty bank account, her trust is destroyed and she’s vowed never to fall for a man again. Instead, she’s only in the mood for one-stands. Not Happy Ever After’s.

But when a mysterious passenger orders a drink from her, she’s powerless to resist him. And soon one night turns into stolen and illicit moments at every opportunity. But romances with the passengers are strictly forbidden... and Kelsey is enjoying breaking all the rules.

Brooding billionaire Ari Callisthenes, heir to a Greek shipping line is undercover on his own cruise liner. His standards are impossibly high but his business is underperforming. He’s determined to find out why. However, he doesn’t expect the instantaneous chemistry with sexy cocktail waitress Kelsey or the whirlwind fling they find themselves entangled in. She awakens a part of himself he believed dead. But a future together is out of the question because he can’t tell her who he is...
