The deeper they dig, the darker the rabbit hole becomes.

Renowned surgeon Harrison O'Rourke is starting to panic. His two friends said they were going on a trip, but a month has passed with no word and no trace of them anywhere. When the trail leads him to Chicago's shadowy Aces Underground, Harrison forces his way inside, determined to look for clues.

Bianca Montrose once chased Broadway dreams, but New York chewed her up and spit her out. Now she sings in the smoky corners of her sister's exclusive underground club, a place built on secrets and silence. When handsome Harrison O'Rourke slips inside looking for answers, Bianca smuggles him in...and one charged moment between them sparks a chemistry neither can ignore.

Their attraction is instant. Their connection is dangerous.

And the club is watching.

As Harrison and Bianca begin peeling back the layers of Aces Underground, they uncover whispers, lies, and a network of power that doesn't tolerate curiosity. Every step pulls them toward the truth as secrets sharpen, danger rises, and the fire between them blazes hotter.

Together, they might expose Aces Underground...or be swallowed by it.
