Months after Dr. Elena Marquez vanished into the Interstice, strange transmissions begin rippling through the world’s radio bands, frequencies that defy physics, voices whispering names of the living, and stars rearranging themselves into unfamiliar constellations. When Kael awakens in the ruins of the Elbrus Observatory with fragments of Elena’s voice echoing in his mind, he realizes the signal didn’t end with her it evolved. As reality bends under invisible harmonics, Kael must follow the Hollow Signal to its source, uncovering a truth that threatens not just the boundaries of space, but the meaning of being human.

About the author
Smith Daniel
Smith Daniel is a speculative fiction writer whose work explores the fragile boundaries between memory, identity, and the cosmos. With a background in astrophysics and philosophy, he weaves narratives where science and emotion collide. His stories often begin with a whisper from the void—then unravel into questions no one intended to ask.
When he isn’t writing, Smith can be found stargazing through a telescope, sketching star maps on napkins, or restoring old mechanical watches in his workshop.View all audiobooks by Smith Daniel
