The Last Signal

When a dying beacon begins pulsing from the forbidden wilderness known as the Deadfall, rescue captain Sloane Reeves follows a trail of relics left by an expedition that vanished without a trace. Every clue draws her deeper into collapsing caves, deadly weather, and a mystery the wild itself seems determined to bury. But finding the last survivor is only half the rescue—because he refuses to leave, and whatever he’s guarding may be the reason they went in at all.
