The Syndicator - book 6

It ends where it begins. . .
Years ago, four dangerous men and a mysterious negotiator gathered in the shadows to broker a deal that would shape the future of the Tenebrae Outfit forever.
Now, the criminal world they created is far darker – far more dangerous – than anyone could have ever imagined.
To survive, four couples – tied to one another in ways none of them understand – must work together to uncover the mob’s deadliest secrets and break free from the darkness that made them.
If they succeed? A new generation is born.
