Two signals arrive from deep space.
Both are impossibly precise. Both encode pure mathematics. And both were sent untold millennia ago.
When the new NEEDLES detection system isolates the transmissions, journalist Brynn Parry is drawn into what first appears to be a minor scientific curiosity. Instead, he finds himself at the centre of the most significant discovery in human history.
At the same time, Maria Gaviota’s research into primate brain activity reveals patterns that are disturbingly familiar — as though intelligence itself leaves a universal signature.
As evidence mounts, science, faith and reason begin to collide. Because if the messages were deliberate, then someone, somewhere, reached out across the stars. And humanity must decide what that means.
