At exactly 11:11, the signal begins.
Thirteen-year-old Arjun and his three friends discover a mysterious radio signal that should not exist. What starts as a strange transmission soon leads them to Project Echo, a secret experiment involving messages from another time.
But the deeper they investigate, the stranger things become. Their school seems to remember events that never happened. A boy claiming to be from the future appears. Memories begin to change, and the friends realize that their actions may be affecting the timeline itself.
Now, they must uncover who is sending the signal—and why.
Because the last signal isn't just a warning. It's an invitation.
The Last Signal is a science-fiction mystery adventure about friendship, courage, time, and the consequences of changing the future.
