Jeth Hollins is just a courier-a runner of messages, not a hero. But when the floating city of Acosis begins to collapse during a routine gravity shift, he and his partner Alynna witness something they were never meant to see.
The city isn't malfunctioning.
It's being silenced.
As the government blames foreign sabotage and suppresses the truth, Jeth and Alynna race against time to expose the real cause before the next shift turns catastrophic. But the deeper they dig, the more dangerous the truth becomes-and in a city suspended in the sky, one wrong step can bring everything crashing down.
One city. One secret. One final chance to be heard.
Set in the steampunk-inspired world of Aerithen, Threat Level: Acosis is a high-stakes YA novella packed with heart-pounding tension, emotional weight, and the courage of ordinary people who refuse to stay silent.
Perfect for fans of Scythe, Skyward, and Arcane.
