The rainforest let them go. Janice Gold never did.
Oregon City, 2027. On her deathbed, neurosurgeon Dr. Claudia Gold makes her granddaughter promise one thing: when I'm gone, let me be gone. Nobody opens my head. Janice cannot promise that. She has a lab under the house, a volcano in Costa Rica, and a theorem her grandmother spent forty years saying was impossible.
A year after the retreat, the Xenon team is drifting apart. Jason and Jake have gone quiet since taking jobs with ONOS BIO. Then the offer letters arrive, each with a personal note from Janice: double salary, two weeks in Oregon City, a permanent post in the rainforest. One by one they download Taylor Street and say yes. Matt owes it to Tommy Hagle to find out what really happened. Mishka wants her name on the project that lets people live forever. Susan just wants a fresh start for her daughter.
Back in the jungle, Trevor and Jason are still trying to walk out, with a broken-beaked toucan named Gronky leading and Bruno somewhere behind them. Eighteen chapters, from Root Directory to Claudia.
