The Coldest Obsession
(2026)(The third book in the Valentino Kings series)
A novel by Sienna Marchetti
He runs the numbers. She's the variable he can't solve.
Luca Valentino is the quiet one. The analyst. The brother who dismantles empires with spreadsheets instead of bullets. He doesn't do impulse, chaos, or feelings that can't be quantified.
Then Valentina walks into his office with a legal case that could destroy his family — and a coffee order she remembers perfectly by day three.
She's supposed to be the enemy. He's supposed to be smarter than this.
Val is a lawyer with a spine made of steel and a tongue sharp enough to draw blood in any courtroom. She wasn't hired to fall for the man whose family she's investigating. But Luca notices everything — the way she takes her coffee, the argument she's building, the wall she's hiding behind — and he's decided that solving her is more interesting than saving himself.
When a betrayal inside the family threatens to bring the Valentino empire crashing down, Luca and Val will discover that the coldest obsession burns the hottest — and that some equations only balance when you stop trying to control the outcome.
The Coldest Obsession is a full-length standalone mafia romance with enemies to lovers tension, a brainy hero, explicit steam, and an HEA. Book 3 in The Valentino Kings series.
Genre: Romance
