The sky is no longer a frontier-it's a prison. Ava Renn has spent her life scavenging the toxic skies of a ruined Earth, surviving one deadly storm at a time. But when she intercepts a mysterious encrypted signal, it leads her to Aegis One-a massive orbital prison long believed to be dead. It isn't. Inside the decaying station, survivors have carved out a brutal new society ruled by fear, factions, and a shadowy figure known only as the Overseer. As Ava is drawn deeper into a world of violence, hidden power, and a dangerous AI system that may still control the prison itself, she realizes the beacon wasn't a call for help-it was a lure. Now trapped in a crumbling fortress above a dying world, Ava must navigate shifting alliances, uncover the truth behind the Overseer, and find a way to escape before the prison claims her... or turns her into part of it. Dark, gripping, and relentlessly tense, The Sky Prison is a high-stakes sci-fi thriller of survival, power, and the cost of freedom in a world that has already fallen.
