After barely surviving the fire that was supposed to end everything, Adaliya wakes up in a hospital, scarred inside and out. But the horrors of the Backrooms didn't die with the house-they've escaped, and now the creatures that haunted her are loose in the real world. As the ASYNC Foundation struggles to contain the breach, Adaliya is forced to confront the nightmare once again. With humanity on the brink of collapse, Adaliya must decide if she can trust the very people who started it all. Driven by grief, guilt, and rage, she's the only one with the knowledge to stop the creatures before they tear reality apart-but the lines between friend and foe are blurred, and not everything, or everyone, is as they seem. In this explosive final chapter, Adaliya faces her greatest challenge yet: a showdown against the forces that shattered her world. Will she find a way to seal the Backrooms for good, or is this truly the end of the line?
