Viola Costa never asked to work with Leonardo Russo.
To her, he's a rival-too calm, too observant, too involved in her cases. A detective who questions her instincts, challenges her authority, and turns every investigation into a silent competition. She keeps her distance, keeps her guard up, and calls him "Leo" only when frustration or fear slips past her control.
What Viola doesn't know is that Leonardo Russo has already lost the fight.
He fights like there is no tomorrow because once, he had nothing to lose.
Until she became his everything.
From the very beginning, Leo watches over her in ways she never notices-stepping into danger first, memorizing her habits, protecting her without asking permission. Daisy flowers appear without a name. Cookies-and-cream ice cream shows up after her hardest shifts. He never explains. He never confesses. Loving her is something he does quietly, deliberately, and completely.
As a dangerous case tightens its grip on the streets of Italy, rivalry turns into forced partnership, and forced partnership into undeniable tension. Viola begins to see past the arrogance, past the competition, and into the man who has been choosing her long before she chose him back.
Because some cases aren't just about justice.
Some are about restraint.
Some are about devotion.
And some stay forever between two people.
The Case Between Us is a slow-burn crime romance about loving first, fighting silently, and the moment an enemy becomes home.
