Undeniably Enemies: A Brother's Best Friend, Age Gap Romance (Boston's Irresistible Billionaires Book 5)

Years ago, a man slept with his best friend's younger sister at a Halloween party, then ruined everything—twice. Now they work together at a hospital where she is a medical student and he is an attending physician. They also live in neighboring apartments, neither realizing the connection until after the fact. Their relationship is marked by legendary animosity, yet he cannot stop thinking about her or that night. When she discovers secrets he has been keeping, their anger transforms into passion. He knows he should maintain distance—she is younger, and a relationship would threaten the life he has rebuilt. But he has never wanted anyone more. Complicating matters further, she too is keeping secrets. The story follows their journey as enemies, with an age gap of ten years, navigating their professional and personal entanglement while contending with unresolved feelings and hidden truths. The narrative includes explicit content and concludes with a happy ending.
