The Silence Below

When structural engineer Evan Cole is sent to inspect a remote hydroelectric dam after reports of strange vibrations, he expects faulty machinery-not whispers echoing through concrete walls. Deep beneath the waterline, the rhythmic tremors form patterns no machine could make. As Evan descends into the dam's tunnels, his radio begins repeating fragments of his past, words only his late father would know.
The deeper he goes, the louder the voices become-until he uncovers a sealed chamber marked Project Echo, a forgotten experiment in sound and consciousness. With the dam on the verge of collapse and the whispers begging to be freed, Evan must face an impossible choice: silence the trapped voices forever or join them in the dark below. The Silence Below is a chilling psychological thriller about secrets that don't stay buried and the echoes of guilt that never die.
