Last Signal Tower

Lucas Ward works the night shift in Signal Tower 12, an aging railway post scheduled for closure. He knows every sound in the building, every flicker in the panel, every quirk of the old machinery. So when he starts hearing radio transmissions from a decommissioned line, he knows he isn't imagining it.At first, it is just a fragment. A signal. A pattern. Then the sensors on the dead branch line begin to activate.What Lucas uncovers is far larger than a ghost in the system. Hidden in the mountains is a covert freight operation moving hazardous industrial waste through forgotten infrastructure no one is supposed to be using. The farther he digs, the clearer it becomes that the trains are real, the danger is growing, and powerful people have spent years making sure no one asks the right questions.With help from a network engineer, a sheriff with old ties to the case, and buried evidence stretching back decades, Lucas finds himself in a race against time to expose a secret built on silence, contamination, and corporate cover-up.The Last Signal Tower is a tense, atmospheric thriller about machinery, memory, and the cost of paying attention when the world would rather look away.
