Forbidden Desire: A Brother's Best Friend Billionaire Romance

By: Whitlock, Amara

He was her brother's best friend. She was his forbidden obsession. Eight years of wanting. One unforgettable night.

LILY CHEN made a mistake when she was eighteen years old.

She kissed Dominic Russo-her brother Marcus's best friend, the boy she'd been crushing on for years, the man who made her heart race every time he walked into a room.

He didn't kiss her back. And the next day, she left for Europe, convinced she'd ruined everything.

Eight years later, she's returned to New York with a career, confidence, and absolutely no intention of falling for him again.

Except Dominic Russo is now a billionaire CEO. Devastatingly handsome. Dangerously charming. And apparently, he's been thinking about that kiss for eight years too.

DOMINIC RUSSO has three rules:
1. Build his empire
2. Stay loyal to his best friend Marcus
3. Never, ever touch Marcus's little sister

He's broken rule number three. Spectacularly.

When Marcus gets engaged, Dominic and Lily are thrust together as best man and maid of honor. Six months of wedding planning. Six months of pretending they don't want each other. Six months of fighting an attraction that's been building for nearly a decade.

One cake tasting leads to a kiss. One kiss leads to a secret relationship. And one secret relationship leads to consequences neither of them saw coming.

But Marcus isn't stupid. And when he discovers his best friend has been dating his sister behind his back, Dominic and Lily face an impossible choice:

Give up the love they've waited eight years for... or risk losing Marcus forever.
