Sinful Obsession: A Dark Mafia Romance

by Kendall Jacobs

I went undercover to take down a criminal empire. I didn't plan to fall for its king.

Isadora
The FBI gave me a new name, a fake résumé, and one bring down the DeSantis family.
I'm embedded as their bookkeeper.
Close enough to find the evidence. Close enough to disappear if I'm caught.
There's just one problem.
Luca DeSantis.
The underboss who runs this empire with brutal precision and reads people like open books.
He's suspicious of me from day one.
Every conversation is a chess match. Every look lasts a beat too long.
He's a criminal. A killer. Everything I swore to put behind bars.
But he’s also the most magnetic man I've ever met.
My handler says get closer. Use the attraction. Get the evidence.
But the closer I get, the less I want to destroy him.

Sinful Obsession is a spicy dark mafia enemies-to-lovers romance with a secret identity, forbidden desire, and a slow burn that detonates.

Omg! The spark between Isadora and Luca was fire from the beginning even when they didn’t know it. The suspense building up was amazing! This was definitely a great read!.
