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

One night. One masked stranger. One catastrophic mistake that Fletcher Davenport has never been able to forget—and never been able to fix.

He knew better than to touch his best friend's little sister at that Halloween party. She was supposed to be off-limits, untouchable, completely forbidden. But one look at her and every rule he'd ever made for himself dissolved. Then he ruined it. Twice. And Isla made sure he knew exactly what she thought of him.

Now they're legendary enemies, their mutual hatred a well-documented fact in their Boston social circle. So naturally, fate has other ideas.

Isla is now a medical student at the hospital where Fletcher is an attending physician—her superior, her tormentor, and the man she can't stop thinking about no matter how furiously she tries. As if that weren't complicated enough, he's unknowingly bought the apartment right next to hers. There's no escaping him, and the proximity is making their explosive tension impossible to ignore.

When Isla uncovers the secrets Fletcher has spent years desperately hiding, everything she thought she knew about that night—and about him—shatters. Because the truth doesn't douse the fire between them. It ignites it.

In this steamy contemporary romance set against Boston's elite medical world, two people who built their entire dynamic around hating each other must decide whether the walls they've constructed are worth more than the undeniable, infuriating, breathtaking thing burning between them.

Some enemies are made to surrender.
