Perfect for you if...

You enjoy enemies-to-lovers romance with genuine workplace stakes and a heroine who refuses to be pushed around.
You like banter-heavy stories where the chemistry is electric but the tension stays high because the external conflict is real.
You want a standalone that delivers both heat and humour without requiring you to commit to a series.

Maybe not for you if...

You prefer slow-burn romance where physical chemistry builds gradually rather than reignites from a prior encounter.
You're looking for a hero who isn't morally compromised or who operates outside cutthroat business practices.
You need relationships to develop with transparency from the start, rather than thriving on secrets and compartmentalisation.

About this book

A woman meets an attractive man at a bar and spends a night with him. She later discovers his identity: he is a billionaire attempting to acquire her bookstore. During the day, they are adversaries in a business conflict. At night, they are intimate partners, keeping the two aspects of their relationship strictly separate. She struggles with her attraction to him despite his ruthlessness and determination to take her business, and works to maintain emotional distance while they continue their physical involvement. Billion Dollar Enemy is the first book in the Seattle Billionaires series.
