Signal from the Salt Sea

Centuries after the oceans boiled away, the salt flats of a dead seabed stretch to every horizon. Echo hunter Tarn Harker has spent his life scavenging fossils and fragments from the ruins of a drowned world. But when his battered detector picks up a persistent signal-one that thrums with eerie purpose-he knows it is no echo. It is a summons. The trail leads Tarn and a ragtag crew across scorched deserts into the abyss of a long-buried trench, where they uncover the Ardent, a research vessel impossibly preserved beneath the salt.
Its corridors hum with forgotten power, its logs whisper of experiments gone wrong, and its sealed chambers conceal something alive. and waiting. As the signal grows stronger, the crew realizes they haven't found a relic of the past, but a gateway to something far older-and far more dangerous-than humanity itself. What began as salvage becomes survival, and what waits in the salt sea may not let them leave.
Atmospheric, relentless, and infused with cosmic dread, Signal from the Salt Sea is perfect for fans of Jeff VanderMeer's Annihilation and James S. A. Corey's The Expanse. Step aboard the Ardent, if you dare-but remember, some signals should never be answered.
