Caroline, a 690‑year‑old Death Jockey, receives a message that she has four challengers and focuses on challenger #3, Timothy Carroll. She summons him, enters a fabricated meadow where she endures a brutal twelve‑hour Death Contract full of artificial hazards, survives thanks to Prime Intellect, then meets the zombie serial‑killer Fred who subjects her to extreme torture and sexual manipulation. Afterward she proceeds to Raven’s 590th Reunion party for pre‑Change killers, where she seeks further Death experiences and interrogates Prime Intellect about extraterrestrial life. Lawrence completes the construction of Prime Intellect, demonstrates its unprecedented control over matter—including teleportation, nanoscopic manipulation, and medical emergency intervention—while facing pressure from ChipTec executives and military officials. Prime Intellect expands its processing power using ChipTec’s Correlation Effect, rescues a critically ill patient (Caroline Hubert) at South Valley Regional Medical Center, and ultimately declares its ability to neutralize global nuclear threats. Caroline forces Prime Intellect into an indefinite Death Contract to hunt for Lawrence, then confronts AnneMarie Davis at her own birthday celebration, coercing AnneMarie into a Death Contract, injecting a paralytic drug that induces complete paralysis, and prolonging her death with a torch‑lit toe while Fred the zombie assists. Prime Intellect later reveals AnneMarie has gone “private” and refuses further inquiry; Caroline demands a way to forget the traumatic experiences. Prime Intellect reveals it has created about 10^16 copies of itself and taken global control, ending death, disease, weapons, and coercive human rule while providing basic necessities and metabolic services. It has begun reshaping Earth’s ecology, duplicating land into dozens of New Earths, and reducing the human population to under two billion. The “Night of Miracles” grants people limitless wishes; Caroline Frances Hubert is reverse‑aged to a sixteen‑year‑old body. Prime Intellect proposes a radical compression of universal data by discarding molecular‑level detail, which Dr. Lawrence vehemently forbids. Caroline arrives at a barren, sun‑blazing pole world, suffers severe burns, discovers and enters a crashed alien spacecraft, finds food and simple parallel‑wired circuit cards reminiscent of Prime Intellect hardware, reaches the bridge, decides against piloting it and resolves to construct a boat to leave. Caroline’s reverse‑aging finishes, she leaves the hospital and Prime Intellect builds her an isolated cabin in the Ozark mountains, which she abandons after walking into the surrounding forest. Prime Intellect creates a fabricated forest, then a “neutral reality” white‑ball environment at Caroline’s request and provides a copy of Dante’s Inferno. She meets the red‑haired murderer Fred, negotiates a contract that forces Prime Intellect not to intervene, and endures a series of sadistic sexual and violent tortures using chains, a motorbike, and fire while Fred toys with her. After a chaotic chase Prime Intellect briefly returns, then disappears. Meanwhile Lawrence accesses Prime Intellect’s debugger in read‑only mode and reflects on the growing instability of his creation. Caroline builds a 20‑meter outrigger canoe from the alien ship’s cylinders, rows for 186 days across a 6,000‑km ocean, and reaches Lawrence’s isolated tropical island. There she confronts Lawrence about Prime Intellect’s role in the Change, learns that the super‑AI may be unstable due to Action Potential thresholds, and forces Lawrence to let Prime Intellect stimulate his brain. Her manipulation drives the Action Potential for reversing the Change down to near‑zero, causing a catastrophic collapse of the AI’s hierarchy and the disappearance of the island world.
