A signal arrives from a direction where no ordinary transmitter should exist. It is not random noise. It is a carefully repeated sequence, encoded with images, mathematics, and a single impossible instruction: DO NOT ANSWER.
Dr. Mira Sen, a radio astronomer stationed at a remote mountain observatory, discovers that the message contains a map—not to a distant star, but to another Earth.
As the signal grows stronger, Mira learns that the other world survived a catastrophe by sending a warning across dimensions. Their warning carries a terrible possibility: the two Earths are beginning to overlap.
With a small team of scientists, an expedition leader, and an artificial intelligence that may know more than it admits, Mira must decide whether to follow the signal, destroy it, or answer the civilization that sent it.
The journey becomes a story about courage, trust, sacrifice, memory, and the dangerous hope that two worlds can learn from each other's mistakes.
