The Mafia Devil's Vow.

…He let the fabric fall. No underwear. Nothing to shield me from the full weight of him.
Ooh gosh!..
He was massive.
Thick. Veined. So hard, it looked like it hurt.
My breath caught. My mouth went dry.
“I want you,” he said, stepping closer. “But not like a trophy. Not like something to conquer. I want to own the part of you no one else has touched.”
“Turn around,” he uttered…
“He didn’t ask for my hand. He demanded my life.”
Criminal defense attorney Serena Hale is known for two things: never losing a case, and never letting anyone too close. Scarred by a childhood betrayal, she’s built walls so high even her lovers never see the real her. But when she witnesses a brutal Mafia execution after a high-profile trial, her ironclad world cracks and the Devil steps in.
Adrian De Luca, the enigmatic underboss of the De Luca crime family, offers Serena a choice: marry him and stay under his protection… or die for what she saw. Cold and dangerously seductive, Adrian claims he needs a wife for “business optics.” But Serena knows nothing in the Mafia is ever that simple.
What begins as a hostile union turns into a twisted game of psychological seduction. Adrian’s obsession with Serena burns beneath his icy control and she can’t decide whether to run or surrender. With every touch, sin-stained night, the line between hate and desire blurs.
But in Adrian’s world, secrets are currency and love is a weakness.
Serena thought she was marrying a monster to stay alive.
She never expected to fall in love with him.
In a world where trust kills faster than bullets, what happens when the only person you crave is the one who could destroy you?
