When a global communications blackout strikes without warning, former emergency pilot Eli Cross receives a single mysterious radio signal repeating cryptic coordinates—and a warning: before dawn. With cities falling silent, electronics failing, and the world descending into chaos, Eli must navigate abandoned highways, collapsing towns, and rogue survivors to uncover the source of the signal. Guided by Mara Vance, a former engineer with knowledge of the anomaly, Eli races against time to deliver a fragile message of hope before the silence adapts and spreads. The Last Signal Before Dawn is a pulse-pounding survival thriller about courage, trust, and the lengths humanity will go to reclaim its voice.
