The world didn't end with a bang. It ended with a Hum.
San Francisco, 2084. The Aura Network rules everything.
Sixty years ago, a grid of towers was built to power the city. Instead, it turned the air itself into a weapon - a constant, crushing frequency called the Hum that shatters bones, burns out minds, and transforms people into "Vibes" hollow, twitching creatures vibrating apart from the inside out.
Kaelen - known only as Ghost - is fifteen, deaf, and one of the only people who can survive the Static. She doesn't hear the Hum. She feels it. And that difference is the only thing keeping her alive.
When she rescues Jace from the ruins of the city, she gets more than she bargained for. He's not just a survivor - he's the son of the Architect, the man who built the Network and designed the end of the world. Now Kaelen and Jace are racing toward the Needle, the tower at the heart of it all, with five hundred Mutes and Resonators at their backs and the most powerful man in the world waiting for them at the top.
To destroy the frequency, she'll have to become it.
For readers of Marie Lu, Neal Shusterman, and Pierce Brown.
In a world where sound is the weapon, silence is the revolution.
