Some doors should never be opened. Some friends are already lost...

Deep in the state forest, residents and hikers have been vanishing without a trace. The local sheriff calls them missing… And the missing persons posters keep multiplying on the bulletin board at the station.

When engineer Tom McKenzie and his best friend Howie Craven discover a shimmering, portal-like anomaly that defies logic, Tom's analytical mind searches for a rational explanation.

They leave the area…

Promise to report…

And promise to stay away…

But Howie's curiosity proves stronger than caution. He goes back gets sucked in and the spiritless inhabitants aren't mindless predators. They're following orders from something ancient and infinitely patient, something that had been waiting decades for the right person to open the right door at exactly the wrong time!

Perfect for readers who loved Bird Box, The Ritual, and Annihilation—a cosmic horror that proves the most terrifying predators are the ones who know exactly how much you love the people you'd die to save.

Warning: Contains graphic horror elements, body horror, and psychological terror. Not recommended for readers seeking light supernatural fiction.
