The Echo of the Maw

When architect Elias Thorne is randomly teleported to a hellish shore, he becomes the latest meal for a cosmic horror. He is devoured alive, only to awaken back in his reality, physically whole but spiritually shattered. Now, he can see the other survivors—the haunted, the broken, the "Marked"—hiding in plain sight. He discovers he wasn't just a victim; he was a witness. And the entity that fed on him is getting hungrier.
