Daniel Hart has everything — old money and a carefully constructed life. There's just one problem. He's a polygamist.

When Daniel disappears on October the fourth, three missing persons reports land on Detective Raglan's desk. Then Hart and Associates — the family firm — files the fourth. Nobody can find Daniel Hart, dead or alive. Where is he?

As the case turns federal and FBI Special Agent Kira Cross starts pulling threads, she finds something nobody expected — Daniel's parents, Aaron and Genny Hart, died in a tragic accident fourteen months ago. Kira doesn't believe in accidents, neither does Kristian Cain.

This story didn't start with a missing husband. It started twenty years ago, culminating in a government conspiracy no-one saw coming.

Behind the grieving wives, the inherited fortune, and the unanswered questions, something far darker is waiting — and the Hudson doesn't give up its secrets easily.

The truth doesn't hide in the shadows. It doesn't hide in plain sight. It hides in the Darkdown.
