I was trained to bring down criminals like Finn O'Rourke.

Instead, I became his obsession.

Federal prosecutor Sophia Rivera has never lost a case. Cold, calculating, and completely focused on justice-until she's assigned to infiltrate the most dangerous man in Boston.

Finn O'Rourke built his empire on blood and bullets. The Irish mafia boss controls everything from the shadows, and no one has ever gotten close enough to bring him down.

Going undercover should have been simple. Seduce the target. Gather evidence. Destroy his organization.

But the moment our eyes meet across that crowded ballroom, everything changes.

He sees right through my lies. I see past his darkness. And neither of us can walk away.

One touch ignites a fire that threatens to burn down everything I believe in. One night in his arms, and I'm lost to a man I should hate. When I discover I'm carrying his child, the choice becomes impossible.

Betray the badge I've sworn to uphold, or lose the only man I've ever loved.

But Finn O'Rourke isn't just a criminal-he's the key to exposing a conspiracy that reaches the highest levels of government. Senators playing god with innocent lives. Federal agents selling justice to the highest bidder. A shadow network that will kill anyone who threatens their power.

They took everything from us. Now we're taking it all back.

Some lines can't be uncrossed. Some sins can't be forgiven. But when love collides with loyalty, when desire wars with duty, there's only one rule that matters:

Protect your family at any cost.

Even if it means burning the whole system to the ground.
