There is a pocket of the Amazon that the maps still show as unbroken green. No expedition has ever lasted inside it. The peoples who live at its edge call it "the place where voices don't come back."

When biologist Rachel Hayes enters it with four companions, she expects to find undiscovered life. She finds something else. Up there, a hundred and fifty feet above the ground, in the second forest floor the canopy makes, something is watching. Something that lets invisible threads hang down to mark its prey. Something that takes their voices first—so no one hears where it carries them.

One by one, they vanish. Without a sound. All that's left are drops of blood falling in silence onto the leaves.

And the one rule that might keep them alive is the one rule no human can keep: never look up.

The Silent Ones is relentless, realistic creature horror, suffocating, immersive, impossible to put down.
