A severed cable in the Luzon Strait. A warship crippled by a sudden systems failure in the Sea of Japan. A distress signal transmitted on a frequency that should not exist.
Three incidents. Three oceans. Less than two days apart.
Individually, they can be explained. Together, they point to something far more dangerous.
Master Chief Elspeth Renner spends her days aboard an aging Navy intelligence ship, listening to the noise of the world's most volatile waters. For months, there has been nothing unusual.
Until now.
A pattern is emerging, hidden in plain sight. Elspeth recognizes it because she missed it once before, and the cost was measured in lives.
As the signs multiply and the warnings go unanswered, she faces a terrifying possibility: a crisis is already unfolding. And if she cannot convince the right people in time, the next signal may be the one that starts a war.
