2) Vince & Elle: Discreet Series by Willow Winters

Book #2 of the Discreet Series

Tropes: Mafia Romance

His Hostage is the second standalone novel within the Valetti Crime Family Series.

Blurb:

I was innocent before him, and he wanted nothing more than to ruin me.
And if I’m honest, I wanted him too, even knowing I shouldn’t.

I knew he was a bad man, it doesn’t take more than a single look to know it.
Dark eyes and a charming smile that’s made to fool girls like me.
Still, I caved; I gave into temptation.

And then I saw something I shouldn’t have.
Wrong place, wrong time. The mafia doesn’t let witnesses simply walk away.

Regret has a name, and it’s Vincent Valetti.
He won’t let them kill me, but he’s not going to let me go either.
