Will Voss built a wormhole in his garage with math, stubbornness, and an unreasonable amount of duct tape. Getting there wasn't the hard part. Getting back is. Now he's sharing his nervous system with Carl — a billion-year-old consciousness that has decided Will's body is a renovation project and is not asking permission. First contact is not going well. The upgrades are real. Will's hands can fold space. His body is becoming something not entirely human. And the planet has started to notice. Because this world has an immune system. And it does not like intruders. Warranty Extended is a sci-fi progression adventure about an engineer who solves problems by taking them apart — even when the pieces are alive, lying, or trying to rewrite him from the inside out.
