Pulse

Dr. Ray Godfrey has left behind his wife, his city, and the last fragile peace of a world tilting toward war.
His mission: study an impossible pulse at the edge of known space. But as the signal shifts, so does everything else—data falters; time fractures; something begins to speak through the silence.
Haunted by what he’s lost—and driven by what he cannot explain—Ray descends into obsession, suspended between duty, memory, and a presence far older than understanding.
Pulse is a slow-burn descent into cosmic dread, psychological unraveling, and the cold hush of the unknown—where all things must yield.

For readers who loved the monomaniacal chase of Moby-Dick, the unfathomable intelligence of Solaris, the uncanny isolation of Annihilation, the hard-SF horror of Blindsight, and the eldritch revelation of At the Mountains of Madness, Pulse delivers them all in one gripping voyage into the void.
