Black Widow’s Kiss by Alex McAnders

What do you get when you marry a calculating mobster to the infamous “Black Widow” of the yakuza?

A union soaked in blood and betrayal.

I never expected to be getting married, especially not to the most dangerous figure in the Sato family. But when a chance to strengthen our family’s grip on New York’s underworld presents itself, I know I can’t refuse. My loyalty to the Ricci name demands this sacrifice, even if it means tying my fate to someone who might be plotting my demise.
But nothing is as it seems. Instead of a ruthless killer, Kuroi Sato turns out to be a chaotic force of nature—unpredictable, deadly, and irresistibly captivating. Born from a scandalous union that nearly destroyed his father’s empire, he’s nothing like the silent assassin I expected; he’s a storm that threatens to pull me under if he’s not handcuffed, disciplined, and marked.
As I dig deeper into the secrets surrounding Kuroi, every clue points back to him looking to make me his next meal. But the closer I get to the truth, the more I realize that our lives are entwined in ways I never imagined.

In a city where loyalty is power and blood is the price, there’s no escape. I’ll either conquer his heart or join the graves of his past lovers.
