How much would you sacrifice to be free of your past?

Blackthorn Lodge is an elite psychological retreat deep in the Olympic Mountains—a place for the powerful and the broken, where guests surrender their names, their histories, and their outside lives.

No phones. No contact. And no way down the mountain until The Curator says you’re ready.

When a guest vanishes from the sanctuary without a trace, Silas West is asked to go in quietly under a false name. Just observe, report back. Nothing more. But when a body surfaces, it becomes clear that the man they call The Curator isn’t leading therapy—he’s leading something else entirely.

And now no one is allowed to leave. Including Silas.

Soon, he’s not just watching the experiment—he’s part of it. And learning that while some retreats promise transformation, this one demands it.

Grab The Sin Collector today, the second book in the gripping new psychological mystery series from #1 international bestseller D.D. Black.
