After a viral rescue video exposes her glitchy Gravity Anchor, sixteen-year-old Floater Ava Ward is invited to the elite Gravity Academy—but only to test a dangerous prototype. Inside the device lives Aero, an illegal AI with a sarcastic personality and a terrifying secret: the Academy is deliberately destabilizing gravity in poor districts to keep them dependent. As Ava's body begins losing all gravitational stability, she teams up with misfit trainees to expose the conspiracy before the world's gravity system collapses completely. But saving everyone means sacrificing the one thing keeping her grounded.
