The signal no longer needs everyone to hear the same thing.

It only needs them to keep listening.

Across Britain and beyond, impossible events are becoming harder to contain. Railway stations remember futures that never happened. Familiar voices offer help they were never asked to give. Different versions of people, places and histories begin to overlap without warning.

And beneath it all, the receiver network is still growing.

Daniel Merrick thought humanity had bought itself time by refusing to let LASTLIGHT decide which reality was real. But the system has adapted. Agreement is no longer necessary. Meaning is no longer necessary.

Only connection.

As Daniel, Louise, Helen, Halden, Aisha and the others race to understand what the Final Broadcast actually is, they uncover the truth about LASTLIGHT's earliest experiments, the mysterious Receiver-4791, and the role Daniel was never meant to carry forever.

But the greatest danger may not be the signal itself.

It may be the human instinct to make everything understandable.

To connect every person.

Map every reality.

Resolve every contradiction.

Because when every place can reach every other place, and every version of a person can be found, the thing beyond the signal may no longer need to search for humanity.

Humanity may have made itself impossible to miss.

The Final Broadcast is the concluding book in The Last light Trilogy, a British science-fiction horror series blending cosmic dread, psychological suspense, reality distortion and survival thriller tension.
