Some discoveries should stay buried among the stars.

Lieutenant Erynn Kade has spent her career chasing the ghosts of extinct civilizations ? but she's never expected one to answer back.

When her research vessel, the Celestial Dawn, intercepts an impossible transmission from deep space, Erynn is faced with something science can't explain: a signal from the Eidari, a species that has been silent for thousands of years. It's not a remnant. It's not an echo.

It's a warning.

As Erynn deciphers fragments of an alien language, she uncovers traces of a catastrophe that consumed an entire civilization ? and chilling evidence that humanity may be next. But the truth is only half the battle. Someone aboard the Celestial Dawn doesn't want it found. Old loyalties fracture. Hidden agendas surface. And whatever sent that signal is still out there, still listening ? and now it knows they heard it.

From the quiet corridors of a research ship to the edge of uncharted space, The Lost Signal is a haunting journey through discovery, sacrifice, and the terrifying cost of remembering what the universe wants buried.
